1 DELETE
The DELETE command performs the following functions:
o Deletes one or more files from a mass storage disk volume (see
File).
o Deletes the definition of a queue characteristic previously
established with the DEFINE/CHARACTERISTIC command (see
/CHARACTERISTIC).
o Deletes one or more active bitmaps (see /BITMAP).
o Deletes one or more print or batch jobs. The jobs can be in
progress or waiting in the queue (see /ENTRY).
o Deletes a form (for printer or terminal queues) previously
established with the DEFINE/FORM command (see /FORM).
o Removes an entry from the break-in database (see /INTRUSION_
RECORD).
o Deletes key definitions that have been established by the
DEFINE/KEY command (see /KEY).
o Deletes a print or batch queue created by the INITIALIZE/QUEUE
command, and deletes all the jobs in the queue (see /QUEUE).
o Deletes one or all symbol definitions from a local or global
symbol table (see /SYMBOL).
2 file
Deletes one or more files from a mass storage disk volume.
Requires delete (D) access to the file and write (W) access to
the parent directory. If the target file is itself a directory,
the directory must be empty.
Format
DELETE filespec[,...]
3 Parameter
filespec[,...]
Specifies the names of one or more files to be deleted from a
mass storage disk volume. The first file specification must
contain an explicit or default directory specification plus an
explicit file name, file type, and version number. Subsequent
file specifications need contain only a version number; the
defaults will come from the preceding specification. The asterisk
(*) and the percent sign (%) wildcard characters can be used in
any of the file specification fields.
If you omit the directory specification or device name, the
current default device and directory are assumed.
If the file specification contains a null version number (a
semicolon (;) followed by no file version number), a version
number of 0, or one or more spaces in the version number, the
latest version of the file is deleted.
To delete more than one file, separate the file specifications
with either commas (,) or plus signs (+).
3 Qualifiers
/BACKUP
Modifies the time value specified with the /BEFORE or the
/SINCE qualifier. The /BACKUP qualifier selects files according
to the dates of their most recent backups. This qualifier
is incompatible with the /CREATED, /EXPIRED, and /MODIFIED
qualifiers, which also allow you to select files according
to time attributes. If you specify none of these four time
qualifiers, the default is the /CREATED qualifier.
/BEFORE
/BEFORE[=time]
Selects only those files dated prior to the specified time. You
can specify time as absolute time, as a combination of absolute
and delta times, or as one of the following keywords: BOOT,
LOGIN, TODAY (default), TOMORROW, or YESTERDAY. Specify one of
the following qualifiers with the /BEFORE qualifier to indicate
the time attribute to be used as the basis for selection:
/BACKUP, /CREATED (default), /EXPIRED, or /MODIFIED.
For complete information on specifying time values, refer to the
OpenVMS User's Manual or the online help topic DCL_Tips (subtopic
Date_Time).
/BITMAP
/BITMAP=n,x
Enables the system manager to delete one or more active bitmaps
to make memory resources available. If a bitmap is deleted, then
former virtual unit members can only be added with a full copy.
Requires ownership of the device or VOLPRO protection.
For additional information on bitmaps, refer to Volume Shadowing
for OpenVMS.
/BY_OWNER
/BY_OWNER[=uic]
Selects only those files whose owner user identification code
(UIC) matches the specified owner UIC. The default UIC is that of
the current process.
Specify the UIC by using standard UIC format as described in the
OpenVMS Guide to System Security.
/CONFIRM
/CONFIRM
/NOCONFIRM (default)
Controls whether a request is issued before each delete operation
to confirm that the operation should be performed on that file.
The following responses are valid:
YES NO QUIT
TRUE FALSE Ctrl/Z
1 0 ALL
<Return>
You can use any combination of uppercase and lowercase letters
for word responses. Word responses can be abbreviated to one or
more letters (for example, T, TR, or TRU for TRUE), but these
abbreviations must be unique. Affirmative answers are YES, TRUE,
and 1. Negative answers include: NO, FALSE, 0, and pressing
Return. Entering QUIT or pressing Ctrl/Z indicates that you want
to stop processing the command at that point. When you respond by
entering ALL, the command continues to process, but no further
prompts are given. If you type a response other than one of
those in the list, DCL issues an error message and redisplays
the prompt.
/CREATED
/CREATED (default)
Modifies the time value specified with the /BEFORE or the /SINCE
qualifier. The /CREATED qualifier selects files based on their
dates of creation. This qualifier is incompatible with the
/BACKUP, /EXPIRED, and /MODIFIED qualifiers, which also allow
you to select files according to time attributes. If you specify
none of these four time qualifiers, the default is the /CREATED
qualifier.
/ERASE
/ERASE
/NOERASE (default)
When you delete a file, the area in which the file was stored is
returned to the system for future use. The data that was stored
in that location still exists in the system until new data is
written over it. When you specify the /ERASE qualifier, the
storage location is overwritten with a system specified pattern
so that the data no longer exists.
/EXCLUDE
/EXCLUDE=(filespec[,...])
Excludes the specified files from the delete operation. You can
include a directory but not a device in the file specification.
The asterisk (*) and the percent sign (%) wildcard characters
are allowed in the file specification. However, you cannot use
relative version numbers to exclude a specific version. If you
specify only one file, you can omit the parentheses.
/EXPIRED
Modifies the time value specified with the /BEFORE or the /SINCE
qualifier. The /EXPIRED qualifier selects files according to
their expiration dates. (The expiration date is set with the
SET FILE/EXPIRATION_DATE command.) The /EXPIRED qualifier
is incompatible with the /BACKUP, /CREATED, and /MODIFIED
qualifiers, which also allow you to select files according
to time attributes. If you specify none of these four time
qualifiers, the default is the /CREATED qualifier.
/LOG
/LOG
/NOLOG (default)
Controls whether the DELETE command displays the file
specification of each file after its deletion.
/MODIFIED
Modifies the time value specified with the /BEFORE or the /SINCE
qualifier. The /MODIFIED qualifier selects files according to
the dates on which they were last modified. This qualifier
is incompatible with the /BACKUP, /CREATED, and /EXPIRED
qualifiers, which also allow you to select files according
to time attributes. If you specify none of these four time
modifiers, the default is the /CREATED qualifier.
/SINCE
/SINCE[=time]
Selects only those files dated on or after the specified time.
You can specify time as absolute time, as a combination of
absolute and delta times, or as one of the following keywords:
BOOT, LOGIN, TODAY (default), TOMORROW, or YESTERDAY. Specify one
of the following qualifiers with the /SINCE qualifier to indicate
the time attribute to be used as the basis for selection:
/BACKUP, /CREATED (default), /EXPIRED, or /MODIFIED.
For complete information about specifying time values, refer
to the OpenVMS User's Manual or the online help topic DCL_Tips
(subtopic Date_Time).
/STYLE
/STYLE=keyword
Specifies the file name format for display purposes while
deleting files.
The valid keywords for this qualifier are CONDENSED and EXPANDED.
Descriptions are as follows:
Keyword Explanation
CONDENSED Displays the file name representation of what is
(default) generated to fit into a 255-length character string.
This file name may contain a DID or a FID in the file
specification.
EXPANDED Displays the file name representation of what is
stored on disk. This file name does not contain any
DID or FID abbreviations.
The keywords CONDENSED and EXPANDED are mutually exclusive. This
qualifier specifies which file name format is displayed in the
output message, along with the confirmation if requested.
File errors are displayed with the CONDENSED file specification
unless the EXPANDED keyword is specified.
Refer to the OpenVMS Guide to Extended File Specifications for
more information.
3 Examples
1.$ DELETE COMMON.SUM;2
The DELETE command deletes the file COMMON.SUM;2 from the
current default disk and directory.
2.$ DELETE *.OLD;*
The DELETE command deletes all versions of files with file type
.OLD from the default disk directory.
3.$ DELETE ALPHA.TXT;*, BETA;*, GAMMA;*
The DELETE command deletes all versions of the files ALPHA.TXT,
BETA.TXT, and GAMMA.TXT. The command uses the file type of the
first input file as a temporary default. Note, however, that
some form of version number (here specified as the asterisk
(*) wildcards) must be included in each file specification.
4.$ DELETE /BEFORE=15-APR/LOG *.DAT;*
%DELETE-I-FILDEL, DISK2:[MAIN]ASSIGN.DAT;1 deleted (5 block)
%DELETE-I-FILDEL, DISK2:[MAIN]BATCHAVE.DAT;3 deleted (4 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]BATCHAVE.DAT;2 deleted (4 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]BATCHAVE.DAT;1 deleted (4 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]CANCEL.DAT;1 deleted (2 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]DEFINE.DAT;1 deleted (3 blocks)
%DELETE-I-FILDEL, DISK2:[MAIN]EXIT.DAT;1 deleted (1 block)
%DELETE-I-TOTAL, 7 files deleted (23 blocks)
The DELETE command deletes all versions of all files with file
type .DAT that were either created or updated before April 15
of this year. The /LOG qualifier not only displays the name of
each file deleted, but also the total number of files deleted.
5.$ DELETE A.B;
The DELETE command deletes the file A.B with the highest
version number.
6.$ DELETE/CONFIRM/SINCE=TODAY [MEIER.TESTFILES]*.OBJ;*
DISK0:[MEIER.TESTFILES]AVERAG.OBJ;1, delete? [N]:Y
DISK0:[MEIER.TESTFILES]SCANLINE.OBJ;4, delete? [N]:N
DISK0:[MEIER.TESTFILES]SCANLINE.OBJ;3, delete? [N]:N
DISK0:[MEIER.TESTFILES]SCANLINE.OBJ;2, delete? [N]:N
DISK0:[MEIER.TESTFILES]WEATHER.OBJ;3, delete? [N]:Y
The DELETE command examines all versions of files with file
type .OBJ in the subdirectory [MEIER.TESTFILES], and locates
those that were created or modified today. Before deleting each
file, it requests confirmation that the file should be deleted.
The default response-N-is given in brackets.
7.$ DIRECTORY [.SUBTEST]
%DIRECT-W-NOFILES, no files found
$ SET PROTECTION SUBTEST.DIR/PROTECTION=OWNER:D
$ DELETE SUBTEST.DIR;1
Before the directory file SUBTEST.DIR is deleted, the DIRECTORY
command is used to verify that there are no files cataloged
in the directory. The SET PROTECTION command redefines the
protection for the directory file so that it can be deleted;
then the DELETE command deletes it.
8.$ DELETE DALLAS"THOMAS SECRET"::DISK0:[000,000]DECODE.LIS;1
This DELETE command deletes the file DECODE.LIS;1 from the
directory [000,000] on device DISK0 at remote node DALLAS. The
user name and password follow the remote node name.
9.$ DELETE NODE12::"DISK1:DEAL.BIG"
$ DELETE NODE12::DISK1:DEAL.BIG;
Either of these DELETE commands can be used to delete the file
DEAL.BIG on device ZZZ1 at remote node NODE12. Note that the
DELETE command requires an explicit version number in a file
specification, but the file to be deleted is on a remote node
whose file syntax does not recognize version numbers. (NODE12
is an RT-11 node.) Therefore, the file specification must
either be enclosed in quotation marks (" ") or entered with
a null version number (that is, a trailing semicolon [;]).
2 /CHARACTERISTIC
Deletes the definition of a queue characteristic previously
established with the DEFINE/CHARACTERISTIC command. The
/CHARACTERISTIC qualifier is required.
Requires OPER (operator) privilege.
Format
DELETE/CHARACTERISTIC characteristic-name
3 Parameter
characteristic-name
Specifies the name of the characteristic to be deleted.
3 Qualifier
/LOG
/LOG
/NOLOG (default)
Controls whether the DELETE/CHARACTERISTIC command displays the
name of each characteristic after its deletion.
3 Example
$ DEFINE/CHARACTERISTIC BLUE 7
.
.
.
$ DELETE/CHARACTERISTIC BLUE
$ DEFINE/CHARACTERISTIC BLUE_INK 7
The DEFINE/CHARACTERISTIC command in this example establishes
the characteristic BLUE, with number 7, to mean blue ink
ribbons for printers. To change the name of the characteristic,
enter the DELETE/CHARACTERISTIC command. Then enter another
DEFINE/CHARACTERISTIC command to rename the characteristic to
BLUE_INK, using the characteristic number 7.
2 /ENTRY
Deletes one or more print or batch jobs. The jobs can be in
progress or waiting in the queue. The /ENTRY qualifier is
required.
Requires manage (M) access to the queue, or delete (D) access to
the specified jobs.
Format
DELETE/ENTRY=(entry-number[,...]) [queue-name[:]]
3 Parameters
entry-number[,...]
Specifies the entry number (or a list of entry numbers) of jobs
to be deleted. If you specify only one entry number, you can
omit the parentheses. If you do not specify a queue name, you can
delete entries from multiple queues.
The system assigns a unique entry number to each queued print
or batch job in the system. By default, the PRINT and SUBMIT
commands display the entry number when they successfully queue
a job for processing. These commands also create or update the
local symbol $ENTRY to reflect the entry number of the most
recently queued job. To find a job's entry number, enter the
SHOW ENTRY or SHOW QUEUE command.
queue-name[:]
Specifies the name of the queue where the jobs are located. The
queue name can refer either to the queue to which the job was
submitted or to the queue where the job is executing. The queue-
name parameter is optional syntax; however, when you specify a
queue name, the operating system uses it to verify an entry in
the specific queue before deleting the entry.
3 Qualifier
/LOG
/LOG
/NOLOG (default)
Controls whether the DELETE/ENTRY command displays the entry
number of each batch or print job that it deletes.
3 Examples
1.$ PRINT/HOLD ALPHA.TXT
Job ALPHA (queue SYS$PRINT, entry 110) holding
.
.
.
$ DELETE/ENTRY=110 SYS$PRINT
The PRINT command in this example queues a copy of the file
ALPHA.TXT in a HOLD status, to defer its printing until a SET
ENTRY/RELEASE command is entered. The system displays the job
name, the entry number, the name of the queue in which the job
was entered, and the status. Later, the DELETE/ENTRY command
requests that the entry be deleted from the queue SYS$PRINT.
2.$ SUBMIT/AFTER=18:00 WEATHER
Job WEATHER (queue SYS$BATCH, entry 203) holding until 14-DEC-2001
18:00
$ SUBMIT/HOLD/PARAMETERS=SCANLINE DOFOR
Job DOFOR (queue SYS$BATCH, entry 210) holding
.
.
.
$ DELETE/ENTRY=(203,210)/LOG
%DELETE-W-SEARCHFAIL, error searching for 203
-JBC-E-NOSUCHENT, no such entry
%DELETE-I-DELETED, entry 210 aborting or deleted
The SUBMIT commands in this example queue the command
procedures WEATHER.COM and DOFOR.COM for processing as batch
jobs. WEATHER.COM is queued for execution after 6:00 P.M.
DOFOR.COM is queued in a HOLD status and cannot execute
until you enter a SET ENTRY/RELEASE command. Later, the
DELETE/ENTRY/LOG command requests that the system delete both
these entries from the queue and display a message indicating
that the entries have been deleted.
The job WEATHER (entry 203) has completed by the time the
DELETE/ENTRY/LOG command is entered; therefore, entry 203 no
longer exists. Note that a message indicates that there is no
entry 203 in the queue. The job DOFOR (entry 210) is in a HOLD
status when the DELETE/ENTRY/LOG command is entered. Thus, the
system deletes entry 210 from the queue and displays a message
to that effect.
3.$ PRINT CHAPTER8.MEM
Job CHAPTER8 (queue SYS$PRINT, entry 25) pending on queue SYS$PRINT
.
.
.
$ SHOW QUEUE SYS$PRINT
Printer queue SYS$PRINT, on PARROT::PARROT$LPA0, mounted form DEFAULT
Entry Jobname Username Status
----- ------- -------- ------
24 CHAPTER7 SMITH Pending
25 CHAPTER8 SMITH Pending
$ DELETE/ENTRY=25 SYS$PRINT
The PRINT command in this example submits the file CHAPTER8.MEM
to the printer queue SYS$PRINT. Later, user SMITH needs to
edit the file again before printing it. Using the SHOW QUEUE
command, SMITH verifies that the job is still pending and
that the entry number for the job is 25. SMITH then enters
the DELETE/ENTRY command to delete the job from the queue.
2 /FORM
Deletes a form (for printer or terminal queues) previously
established with the DEFINE/FORM command. The /FORM qualifier
is required.
Requires OPER (operator) privilege.
Format
DELETE/FORM form-name
3 Parameter
form-name
Specifies the name of the form to be deleted.
3 Qualifier
/LOG
/LOG
/NOLOG (default)
Controls whether the DELETE/FORM command displays the name of
each form after its deletion.
3 Examples
1.$ DELETE/FORM CENTER
The DELETE/FORM command in this example deletes the form named
CENTER.
2.$ DEFINE/FORM -
_$ /DESCRIPTION="letter size continuous form paper" CFLET 7
.
.
.
$ DELETE/FORM CFLET
$ DEFINE/FORM -
_$ /DESCRIPTION="letter size continuous form paper" LETTER_CONT 7
The DEFINE/FORM command in this example establishes the form
CFLET with number 7 to mean continuous-form paper 8.5 inches
by 11 inches. To change the name of the form, delete the form
named CFLET and define a new one named LETTER_CONT.
2 /INTRUSION_RECORD
Removes an entry from the break-in database.
Requires CMKRNL (change mode to kernel) and SECURITY privileges.
Format
DELETE/INTRUSION_RECORD source
3 Parameter
source
Specifies the name of the device or the remote system where the
user is attempting to log in. The source name can be presented
in the syntax of another operating system domain, for example,
one that is case sensitive or conflicts with DCL syntax rules.
In such cases, you must enclose the source parameter in quotation
marks.
3 Qualifiers
/NODE
/NODE=(node-name[,...])
Deletes the node information relating to the specified nodes. If
the specified nodes are the only nodes in the node information
list, the intrusion record is also deleted.
3 Examples
1.$ DELETE/INTRUSION_RECORD TTC2:
In this example, the DELETE/INTRUSION_RECORD command removes
all intrusion records generated by break-in attempts on TTC2.
No user name is specified because none of the login failures
occurred for valid users.
2.$ DELETE/INTRUSION_RECORD "AV34C2/LC-2-10":FORGETFUL
In this example, the source of the break-in is a local terminal
that is connected to a terminal server. To delete the record
from the break-in database, you must enclose the terminal
port name within quotation marks so that the operating system
interprets the slash as a foreign character and not as a
qualifier.
3.$ DELETE/INTRUSION_RECORD NODE1::HAMMER
This command removes all intrusion entries generated from node
NODE1 for user HAMMER.
4.$ DELETE/INTRUSION_RECORD/NODE=(CAPPY,INDI)
$ SHOW INTRUSION
NETWORK SUSPECT 2 26-JUL-2001 08:51:25.66 BARNEY::HAMMER
Node: TSAVO Count: 2
This command removes intrusion entries for the nodes CAPPY and
INDI.
5.$ DELETE/INTRUSION_RECORD/NODE=FOOBAR
$ SHOW INTRUSION
NETWORK SUSPECT 2 26-JUL-2001 08:51:25.66 BARNEY::HAMMER
Node: TSAVO Count: 2
This command removes intrusion entries for the node FOOBAR.
6.$ DELETE/INTRUSION_RECORD/NODE=TSAVO
$ SHOW INTRUSION
%SHOW-F-NOINTRUDERS, no intrusion records match specification
This command attempts to remove intrusion entries for node
TSAVO, however there were no intrusion records for this node.
2 /KEY
Deletes key definitions that have been established by the
DEFINE/KEY command. The /KEY qualifier is required.
Format
DELETE/KEY [key-name]
3 Parameter
key-name
Specifies the name of the key to be deleted. This parameter is
incompatible with the /ALL qualifier.
3 Qualifiers
/ALL
Deletes all key definitions in the specified state; the default
is the current state. If you use the /ALL qualifier, do not
specify a key name. Use the /STATE qualifier to specify one or
more states.
/LOG
/LOG (default)
/NOLOG
Controls whether messages are displayed indicating that the
specified key definitions have been deleted.
/STATE
/STATE=(state-name[,...])
/NOSTATE (default)
Specifies the name of the state for which the specified key
definition is to be deleted. The default state is the current
state. If you specify only one state name, you can omit the
parentheses. State names can be any alphanumeric string.
3 Examples
1.$ DELETE/KEY/ALL
%DCL-I-DELKEY, DEFAULT key PF1 has been deleted
%DCL-I-DELKEY, DEFAULT key PF2 has been deleted
%DCL-I-DELKEY, DEFAULT key PF3 has been deleted
%DCL-I-DELKEY, DEFAULT key PF4 has been deleted
$
In this example, the user has defined keys PF1 to PF4 in
the default state. The DELETE/KEY command deletes all key
definitions in the current state, which is the default state.
2.$ DEFINE/KEY PF3 "SHOW TIME" /TERMINATE
%DCL-I-DEFKEY, DEFAULT key PF3 has been defined
$ <PF3>
$ SHOW TIME
14-DEC-2001 14:43:59
.
.
.
$ DELETE/KEY PF3
%DCL-I-DELKEY, DEFAULT key PF3 has been deleted
$ <PF3>
$
In this example, the DEFINE/KEY command defines the PF3 key on
the keypad as SHOW TIME. To delete the definition for the PF3
key, use the DELETE/KEY command. When the user presses PF3,
only the system prompt is displayed.
2 /QUEUE
Deletes a print or batch queue created by the INITIALIZE/QUEUE
command, and deletes all the jobs in the queue. The /QUEUE
qualifier is required.
Requires manage (M) access to the queue.
Format
DELETE/QUEUE queue-name[:]
3 Parameter
queue-name[:]
Specifies the name of the queue to be deleted.
3 Qualifier
/LOG
/LOG
/NOLOG (default)
Controls whether the DELETE/QUEUE command displays the name of
each queue after it is deleted.
3 Example
$ INITIALIZE/QUEUE/DEFAULT=FLAG/START/ON=LPA0 LPA0_QUEUE
.
.
.
$ STOP/QUEUE/NEXT LPA0_QUEUE
$ DELETE/QUEUE LPA0_QUEUE
In this example, the first command initializes and starts the
printer queue LPA0_QUEUE. The STOP/QUEUE/NEXT command stops the
queue. The DELETE/QUEUE command deletes the queue.
3 /MANAGER
Deletes a queue manager on a node or VAXcluster system. All
queues and jobs managed by the specified queue manager are also
deleted. You must first stop the queue manager. The /NAME_OF_
MANAGER qualifier is required.
Requires OPER (operator) and SYSNAM (system logical name)
privileges.
Format
DELETE/QUEUE/MANAGER/NAME_OF_MANAGER=name
4 Qualifier
/NAME_OF_MANAGER
/NAME_OF_MANAGER=string
Identifies the name of the queue manager to be deleted. The
/NAME_OF_MANAGER qualifier is required. The required name value
can be up to 31 characters long and can be a logical name.
4 Example
$ DELETE/QUEUE/MANAGER/NAME_OF_MANAGER=BATCH_MANAGER
The DELETE/QUEUE/MANAGER/NAME_OF_MANAGER command in this
example deletes the queue manager named BATCH_MANAGER. The
command removes all references to the specified queue manager
from the shared master file of the queue database and deletes
the queue and journal files associated with the BATCH_MANAGER's
database.
2 /SYMBOL
Deletes one or all symbol definitions from a local or global
symbol table. The /SYMBOL qualifier is required.
Format
DELETE/SYMBOL [symbol-name]
3 Parameter
symbol-name
Specifies the name of the symbol to be deleted. A name is
required unless the /ALL qualifier is specified. The symbol-name
parameter is incompatible with the /ALL qualifier. Symbol names
can have from 1 to 255 characters. By default, the DELETE/SYMBOL
command assumes that the symbol is in the local symbol table for
the current command procedure.
3 Qualifiers
/ALL
Deletes all symbols from the specified table. If you do not
specify either the /LOCAL or the /GLOBAL qualifier, all symbols
defined at the current command level are deleted. The /ALL
qualifier is incompatible with the symbol-name parameter.
/GLOBAL
Deletes the symbol from the global symbol table of the current
process.
/LOCAL
/LOCAL (default)
Deletes the symbol from the local symbol table of the current
process.
/LOG
/LOG
/NOLOG (default)
Controls whether an informational message listing each symbol
being deleted is displayed.
3 Examples
1.$ DELETE/SYMBOL/ALL
In this example, the DELETE/SYMBOL command deletes all symbol
definitions at the current command level.
2.$ DELETE/SYMBOL/LOG KUDOS
%DCL-I-DELSYM, LOCAL symbol KUDOS has been deleted
In this example, the DELETE/SYMBOL command deletes the symbol
KUDOS from the local symbol table for the current process. In
addition, the /LOG qualifier causes an informational message,
listing the symbol being deleted, to be displayed.
3.$ DELETE/SYMBOL/GLOBAL PDEL
In this example, the DELETE/SYMBOL command deletes the symbol
named PDEL from the global symbol table for the current
process.
