VAL(CP) XENIX System V VAL(CP)
Name
val - Validates an SCCS file.
Syntax
val -
val [-s] [-rSID] [-mname] [-ytype] files
Description
val determines if the specified file is an SCCS file meeting
the characteristics specified by the optional argument list.
Arguments to val may appear in any order. The arguments
consist of options, which begin with a -, and named files.
val has a special argument, -, which causes reading of the
standard input until an end-of-file condition is detected.
Each line read is independently processed as if it were a
command line argument list.
val generates diagnostic messages on the standard output for
each command line and file processed and also returns a
single 8-bit code upon exit as described below.
The options are defined as follows. The effects of any
option apply independently to each named file on the command
line:
-s The presence of this argument silences the
diagnostic message normally generated on the
standard output for any error that is
detected while processing each named file on
a given command line.
-rSID The argument value SID (SCCS IDentification
String) is an SCCS delta number. A check is
made to determine if the SID is ambiguous (e.
g., r1 is ambiguous because it physically
does not exist but implies 1.1, 1.2, etc.
which may exist) or invalid (e. g., r1.0 or
r1.1.0 are invalid because neither case can
exist as a valid delta number). If the SID
is valid and not ambiguous, a check is made
to determine if it actually exists.
-mname The argument value name is compared with the
SCCS val.CP keyword in file.
-ytype The argument value type is compared with the
SCCS keyword in file.

The 8-bit code returned by val is a disjunction of the
possible errors, i. e., can be interpreted as a bit string
where (moving from left to right) set bits are interpreted
as follows:
bit 0 = Missing file argument
bit 1 = Unknown or duplicate option
bit 2 = Corrupted SCCS file
bit 3 = Can't open file or file not SCCS
bit 4 = SID is invalid or ambiguous
bit 5 = SID does not exist
bit 6 = , -y mismatch
bit 7 = val.CP, -m mismatch
Note that val can process two or more files on a given
command line and in turn can process multiple command line
(when reading the standard input). In these cases an
aggregate code is returned; a logical OR of the codes
generated for each command line and file processed.

Notes
val can process up to 50 files on a single command line.
