| 1 - SMG$ADD_KEY_DEF |
The Add Key Definition routine adds a keypad key definition to a
table of key definitions.
Format
SMG$ADD_KEY_DEF key-table-id ,key-name [,if-state]
[,attributes] [,equivalence-string]
[,state-string]
1.1 - Returns
OpenVMS usage:cond_value
type: longword (unsigned)
access: write only
mechanism: by value
1.2 - Arguments
key-table-id
OpenVMS usage:identifier
type: longword (unsigned)
access: read only
mechanism: by reference
Identifies the key table to which you are adding a key
definition. The key-table-id argument is the address of an
unsigned longword that contains the key table identifier.
The key table identifier argument is returned by the SMG$CREATE_
KEY_TABLE routine.
key-name
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Identifies the key whose value you are defining. The key-name
argument is the address of a descriptor pointing to this key
name. The SMG$ADD_KEY_DEF routine changes the string to uppercase
and removes trailing blanks.
if-state
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Qualifies the value returned when key-name is pressed. The if-
state argument is the address of a descriptor pointing to the
state string.
If if-state is specified, this definition of key-name is used
only if the current state matches the specified if-state string.
The if-state argument must be from 1 to 31 characters in length.
If this argument is omitted, if-state defaults to the value
DEFAULT.
attributes
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Longword bit mask specifying additional attributes of this key
definition. The attributes argument is the address of an unsigned
longword that contains this attribute mask. If omitted, the mask
is zero.
Valid attributes are described in the following list:
SMG$M_KEY_NOECHO If set, this bit specifies that
equivalence-string is not to be echoed
when this key is pressed. If clear,
equivalence-string is echoed. If SMG$M_
KEY_TERMINATE is not set, SMG$M_KEY_NOECHO
is ignored.
SMG$M_KEY_TERMINATE If set, this bit specifies that when
this key is pressed (as qualified by if-
state) the input line is complete and
more characters should not be accepted.
If clear, more characters may be accepted.
In other words, setting this bit causes
equivalence-string to be treated as a
terminator.
SMG$M_KEY_LOCK If set, and if state-string is specified,
the state name specified by state-string
remains the current state until explicitly
changed by a subsequent keystroke whose
definition includes a state-string. If
clear, the state name specified by state-
string remains in effect only for the next
defined keystroke.
SMG$M_KEY_PROTECTED If set, this bit specifies that this
key definition cannot be modified or
deleted. If clear, the key definition can
be modified or deleted.
The remaining bits are undefined and must be zero. It is possible
to perform a logical OR operation on these values to set more
than one attribute at a time.
equivalence-string
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Character string to be substituted for the keystroke in the
returned line. The equivalence-string argument is the address
of a descriptor pointing to this equivalence string.
The equivalence-string argument is displayed unless SMG$M_KEY_
NOECHO is set. If equivalence-string is omitted, no equivalence
string is defined for this key.
state-string
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Contains a new state name that becomes the current state when
this key is pressed. The state-string argument is the address of
a descriptor pointing to the new state string.
If omitted, no new state is defined. If the current state is
temporary (that is, if SMG$M_KEY_LOCKSTATE was not specified for
the most recently pressed defined key), the current state-string
becomes DEFAULT.

the user can control each virtual display attribute in a single
procedure call. On a single-attribute basis, the user can cause
the following transformations:
Set Complement Action
0 0 Attribute set to default
1 0 Attribute on
0 1 Attribute set to complement of default setting
1 1 Attribute off

through
SMG$M_USER8
The display-id argument must be specified when you use the
rendition-set argument.
rendition-complement
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Attribute complement specifier. The optional rendition-
complement argument is the address of a longword bit mask in
which each attribute set causes the corresponding attribute to
be complemented in the display. All of the attributes that can
be specified with the rendition-set argument can be complemented
with the rendition-complement argument. The display-id argument
must be specified when you use the rendition-complement argument.
The optional arguments rendition-set and rendition-complement
let the user control the attributes of the virtual display. The
rendition-set argument sets certain virtual display attributes,
while rendition-complement complements these attributes. If the
same bit is specified in both the rendition-set and rendition-
complement parameters, rendition-set is evaluated first, followed
by rendition-complement. By using these two parameters together,
the user can control each virtual display attribute in a single
procedure call. On a single-attribute basis, the user can cause
the following transformations:
Set Complement Action
0 0 Attribute set to default
1 0 Attribute on
0 1 Attribute set to complement of default setting
1 1 Attribute off

argument is the address of an unsigned longword that contains
the flag. The default action is to clear the screen when the
pasteboard is created.
Valid values are as follows:
SMG$M_KEEP_ The screen is not initially cleared. The
CONTENTS Screen Management Facility works best when
it can manage the entire screen. Therefore,
using SMG$M_KEEP_CONTENTS is discouraged.
SMG$M_WORKSTATION Calls DECterm to create a DECterm window if
the Screen Management Facility is running on
a workstation that is running DECwindows. If
it is not running on a workstation that is

command completes. The AST-routine argument is the routine's
procedure value.
The AST routine is called with five parameters. The first
parameter is a pointer to a data structure that contains the
display-id, AST-argument, and the command-status values. The
remaining four parameters for the AST routine are R0, R1, PC, and
PSL. The following figure illustrates the AST-routine parameters
and the data structure pointed to by the first parameter.
Parameters to AST Routine data structure
+--------------------------------+ +------------------+
| address of data structure |------>| display-id |
+--------------------------------+ +------------------+
| R0 | | AST-argument |
+--------------------------------+ +------------------+
| R1 | | command-status |
+--------------------------------+ +------------------+
| PC |
+--------------------------------+
| PSL |
+--------------------------------+
If the AST-routine argument is specified, the routine
SMG$EXECUTE_COMMAND buffers any commands passed to it and
executes them in order, calling the specified AST routine when
each command completes. If the AST-routine argument is not
specified, SMG$EXECUTE_COMMAND waits until the specified command
completes before returning control to the user.
AST-argument
OpenVMS usage:user_arg
type: longword (unsigned)
access: read only
mechanism: by value
Optional argument you supply to the AST routine. The AST-argument
parameter is an unsigned longword that contains the value to be
passed to the AST routine.
flags
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Optional argument you supply to SMG$CREATE_SUBPROCESS.
SMG$CREATE_SUBPROCESS calls LIB$SPAWN to create the subprocess.
The flags argument lets you control some of the flags used in
that call. Flags available to SMG$CREATE_SUBPROCESS correspond to
flags in LIB$SPAWN as follows:
SMG$CREATE_ LIB$SPAWN
SUBPROCESS Flag Flag Function
SMG$M_TRUSTED TRUSTED If this bit is set, it indicates
a SPAWN command on behalf of the
application. If this bit is not
set, it indicates that the SPAWN
command originates from the user.
SPAWN commands originating from
users are disallowed in captive
accounts (DCL).
SMG$M_AUTHPRIV AUTHPRIV If this bit is set, the subprocess
inherits the caller's authorized
privileges. If this bit is clear,
the spawned processes' authorized
mask is set equal to the caller's
current (active) privilege mask.
SMG$M_SUBSYSTEM SUBSYSTEM If this bit is set, a spawned
process inherits protected
subsystem IDs for the duration
of LOGINOUT.EXE (used to map the
command line interpreter). The IDs
will be removed in the process of
transferring control to the command
language interpreter (CLI) (as a
user mode $RUNDWN is performed).
If this bit is clear, LOGINOUT does
not execute under the subsystem
IDs.
The default is that none of these bits is set. See online Help or
the OpenVMS RTL Library (LIB$) Manual for a complete description
of LIB$SPAWN, these flags, and the security consideration
surrounding their use.

Display identifier. The display-id argument is the address of
an unsigned longword that contains the display identifier.
This argument is optional only if you are not using the Screen
Management Facility's output routines.
If you are using the Screen Management Facility input and output
routines, this argument specifies the virtual display in which
the input is to occur. The virtual display specified must be
pasted to the same pasteboard as specified by keyboard-id and
must not be occluded. You cannot accept input from an occluded
area of the virtual display.
In the case of multiple virtual displays, each virtual display
has an associated virtual cursor position. At the same time,
there is a single physical cursor position corresponding to
the current location of the physical cursor. If the display-id
argument is specified, the read begins at the current virtual
cursor position in the specified virtual display. If the display
identifier is omitted, the read begins in the current physical
cursor position. The length of the prompt-string plus the key
entered is limited to the number of visible columns in the
display.
NOTE
This virtual display must be pasted in column 1 and may
not have any other virtual displays to its right. This
restriction is necessary because otherwise any occurrence
of Ctrl/R or Ctrl/U would blank out the entire line,
including any output pasted to the right. To circumvent
this restriction, you can use SMG$REPAINT_LINE whenever a
Ctrl/R or Ctrl/U is encountered.
flags

editing is disabled.
SMG$M_NOKEEP Lines entered in the recall buffer are not
saved.
SMG$M_NORECALL Line recall is disabled for this I/O only.
Because the OpenVMS terminal driver uses the function keys (F6 to
F14) for line editing on some terminals, you cannot have function
keys and line editing enabled at the same time.
initial-string
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Optional string that contains the initial characters of the
field. The initial-string argument is the address of a descriptor

OpenVMS usage:longword_signed
type: longword (signed)
access: read only
mechanism: by reference
Optional timeout count. The timeout argument is the address of
a signed longword containing the timeout count. If the timeout
argument is specified, all characters entered before the timeout
are returned in the buffer. If the timeout argument is omitted,
characters are returned in the buffer until a terminator is
encountered.

complement argument is the address of a longword bit mask in
which each attribute set causes the corresponding attribute to
be complemented in the display. All of the attributes that can
be specified with the rendition-set argument can be complemented
with the rendition-complement argument. The display-id argument
must be specified when you use the rendition-complement argument.
The optional arguments rendition-set and rendition-complement
let the user control the attributes of the virtual display. The
rendition-set argument sets certain virtual display attributes,
while rendition-complement complements these attributes. If the
same bit is specified in both the rendition-set and rendition-
complement parameters, rendition-set is evaluated first, followed
by rendition-complement. By using these two parameters together,
the user can control each virtual display attribute in a single
procedure call. On a single-attribute basis, the user can cause
the following transformations:

characters.
TRM$M_TM_NOECHO Characters entered are not echoed on the
screen.
TRM$M_TM_NOEDIT Advanced editing is disabled for this read
operation.
TRM$M_TM_NORECALL Line recall is disabled.
TRM$M_TM_PURGE Type-ahead buffer is purged before read is
begun.
TRM$M_TM_ Termination character, if any, is not
TRMNOECHO displayed.
The TRM$ symbols are defined by the $TRMDEF macro/module in
system symbol libraries supplied by Compaq. See the terminal
driver section of the OpenVMS I/O User's Reference Manual for
more information on modifiers for read operations.
timeout
OpenVMS usage:longword_signed
type: longword (signed)
access: read only
mechanism: by reference
Specifies the number of seconds allowed between the time the
prompt is issued and the completion of the input operation.
The timeout argument is the address of a signed longword that
contains the timeout value.
If timeout is specified, all characters typed before the
expiration time or until a terminate key is entered are returned
in resultant-string. If omitted, the input operation remains
active until a terminator is typed.
terminator-set
OpenVMS usage:unspecified
type: unspecified
access: read only
mechanism: by descriptor, fixed length
Either a mask that specifies which characters are to be treated
as terminators (short form) or a descriptor pointing to such a
mask (long form). The terminator-set argument is the address of a
descriptor pointing to the mask.
If you want to use terminators with ASCII values in the range 0
to 31, use the short form, which consists of two longwords. The
first longword is zero, and the second longword is a terminator
character bit mask. You create this mask by setting the bit that
corresponds to the ASCII value of the desired terminator. For
example, to specify that Ctrl/A (ASCII value 1) is a terminator,
you set bit 1 in the terminator-set mask.
To use terminators with ASCII values outside the range 0 to 31,
use the long form. First create a descriptor of this form:
31 16 15 0
----------------------------------------------------------------
| | |
| (not used) | mask size in bytes |
| | |
----------------------------------------------------------------
| |
| address of mask |
| |
----------------------------------------------------------------
The mask itself has the same format as that of the short form;
however, the long form allows the use of a more comprehensive set
of terminator characters. For example, a mask size of 16 bytes
allows any 7-bit ASCII character to be set as a terminator, while
a mask size of 32 bytes allows any 8-bit character to be set as a
terminator. Any mask size between 1 and 32 bytes is acceptable.
If the terminator mask is all zeros, there are no specified
terminators. In that case, the read terminates when the number
of characters specified in maximum-length has been transferred or
when timeout is reached.
If the terminator-set argument is omitted, the set of terminators
is the OpenVMS default terminator set. For more information, see
the OpenVMS I/O User's Reference Manual.
resultant-length
OpenVMS usage:word_unsigned
type: word (unsigned)
access: write only
mechanism: by reference
Receives the number of characters read or the maximum size
of resultant-string, whichever is less. The resultant-length
argument is the address of an unsigned word into which is written
the number of characters read or the maximum size.
word-terminator-code
OpenVMS usage:word_unsigned
type: word (unsigned)
access: write only
mechanism: by reference
Key terminator code. The word-terminator-code argument is an
unsigned word into which is written a code indicating what
character or key terminated the read. Key terminator codes are
of the form SMG$K_TRM_keyname.
display-id
OpenVMS usage:identifier
type: longword (unsigned)
access: read only
mechanism: by reference
Display identifier. The display-id argument is the address of
an unsigned longword that contains the display identifier.
This argument is optional only if you are not using the Screen
Management Facility's output routines.
If you are using the Screen Management Facility input and output
routines, this argument specifies the virtual display in which
the input is to occur. The virtual display specified must be
pasted to the same pasteboard as specified by keyboard-id and
must not be occluded. You cannot accept input from an occluded
area of the virtual display.
In the case of multiple virtual displays, each virtual display
has an associated virtual cursor position. At the same time,
there is a single physical cursor position corresponding to
the current location of the physical cursor. If the display-id
argument is specified, the read begins at the current virtual
cursor position in the specified virtual display. If display-
id is omitted, the read begins in the current physical cursor
position. Note that the length of the prompt-string plus the
key entered is limited to the number of visible columns in the
display.
NOTE
This virtual display must be pasted in column 1 and may
not have any other virtual displays to its right. This
restriction applies because otherwise the occurrence of a
Ctrl/R or Ctrl/U would cause the entire line to be blanked,
including any output to the right. To circumvent this
restriction, you may use SMG$REPAINT_LINE to repaint the
line when a Ctrl/R or Ctrl/U is detected.
initial-string
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Initial character string. The initial-string argument is the
address of a descriptor pointing to the optional string that
contains the initial characters of the field. The string is
written to the display in the input area, as if it had been
entered from the keyboard. It may be edited in the usual
way (provided that TRM$M_TM_NOEDIT is not set). It must be
shorter than maximum-length, otherwise SMG$READ_STRING returns
immediately without accepting any keyboard input.
rendition-set
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Attribute specifier. The optional rendition-set argument is
the address of a longword bit mask in which each attribute set
causes the corresponding attribute to be set in the display. The
following attributes can be specified using the rendition-set
argument:
SMG$M_BLINK Displays blinking characters.
SMG$M_BOLD Displays characters in higher-than-normal
intensity (bolded).
SMG$M_REVERSE Displays characters in reverse video; that is,
using the opposite default rendition of the
virtual display.
SMG$M_UNDERLINE Displays underlined characters.
SMG$M_INVISIBLE Specifies invisible characters; that is, the
characters exist in the virtual display but do
not appear on the pasteboard.
SMG$M_USER1 Displays user-defined attributes.
through
SMG$M_USER8
The display-id argument must be specified when you use the
rendition-set argument.
rendition-complement
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Attribute complement specifier. The optional rendition-
complement argument is the address of a longword bit mask in
which each attribute set causes the corresponding attribute to
be complemented in the display. All of the attributes that can be
specified with the rendition-set argument can be complemented
with rendition-complement. The display-id argument must be
specified when you use the rendition-complement argument.
The optional arguments rendition-set and rendition-complement let
the user control the attributes of the virtual display in which
the read is done. The rendition-set argument sets certain virtual
display attributes, while rendition-complement complements
these attributes. If the same bit is specified in both the
rendition-set and rendition-complement parameters, rendition-
set is evaluated first, followed by rendition-complement.
By using these two parameters together, the user can control
each virtual display attribute in a single procedure call.
On a single-attribute basis, the user can cause the following
transformations:
Set Complement Action
0 0 Attribute set to default
1 0 Attribute on
0 1 Attribute set to complement of current setting
1 1 Attribute off
terminator-string
OpenVMS usage:char_string
type: character string
access: write only
mechanism: by descriptor
Characters that terminate I/O. The optional terminator-string
argument is the address of a descriptor pointing to the character
string containing the terminating characters. The terminator-
string argument returns the actual terminating characters, not
the key that was pressed to terminate the I/O.

| 116 - SMG$SET_OUT_OF_BAND_ASTS |
The Set Out-of-Band ASTs routine either enables or disables the
trapping of out-of-band control characters.
Format
SMG$SET_OUT_OF_BAND_ASTS pasteboard-id,control-character-mask
,AST-routine [,AST-argument]
116.1 - Returns
OpenVMS usage:cond_value
type: longword (unsigned)
access: write only
mechanism: by value
116.2 - Arguments
pasteboard-id
OpenVMS usage:identifier
type: longword (unsigned)
access: read only
mechanism: by reference
Specifies the pasteboard for which out-of-band characters are
enabled or disabled. The pasteboard-id argument is the address of
an unsigned longword that contains the pasteboard identifier.
The pasteboard identifier is returned by SMG$CREATE_PASTEBOARD.
control-character-mask
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Specifies which control characters are to be the new out-of-band
control characters. The control-character-mask argument is the
address of an unsigned longword that contains the mask. Create
this mask by setting the bit that corresponds to the ASCII value
of the desired character. For example, to specify that Ctrl/C
(ASCII value 3) is an out-of-band control character, set bit 3
(value 8) in the control-character-mask. If no bits are set in
this mask, then no out-of-band ASTs occur. For more information,
see the OpenVMS I/O User's Reference Manual.
AST-routine
OpenVMS usage:ast_procedure
type: procedure value
access: read only
mechanism: by value
The address of an AST routine to be called when an out-of-band
control character is typed at the terminal. The AST-routine
argument is the routine's procedure value.
AST-argument
OpenVMS usage:user_arg
type: longword (unsigned)
access: read only
mechanism: by value
The argument you supply to the AST. AST-argument is an unsigned
longword that contains the value to be passed to the AST routine.
However, the AST routine may also need to determine the out-
of-band character and the pasteboard-id at which it was typed.
Therefore, the Screen Management Facility creates a three-
longword structure to hold this information and passes the
address of this structure as the first argument to the AST
routine. The remaining four arguments are R0, R1, PC, and PSL
(on VAX systems) or PS (on Alpha systems). The Screen Management
Facility stores the argument you supply in this structure.
+---------------------------+ +-------------------------+
| address of data structure |--------->| SMG$L_PBD_ID |
+---------------------------+ +-------------------------+
| R0 | | SMG$L_USER_ARG |
+---------------------------+ +-------------------------+
| R1 | | SMG$L_CHAR |
+---------------------------+ +-------------------------+
| PC |
+---------------------------+
| PSL |
+---------------------------+
The first longword contains the pasteboard-id and has the
symbolic name SMG$L_PBD_ID. The second longword contains the
AST-argument and has the symbolic name SMG$L_USER_ARG. The third
longword contains the ASCII value of the out-of-band character
typed and can be accessed by way of two symbolic names: SMG$B_
CHAR (the low-order byte containing the ASCII value), and SMG$L_
CHAR (the longword containing the ASCII value in the low-order
byte and spaces in the high-order bytes).
