DESCRIPTION

The val command reads files and determines if the specified file is a Source
Code Control System (SCCS) file meeting the characteristics specified by the
flags.  If you specify a - (minus) for file, val reads standard input and
interprets each line of standard input as val flags and the name of an SCCS
file.  val continues to take input until it reaches an end-of-file character
(Ctrl-D).

The val command displays error messages to standard output for each file
processed.  val also returns a single 8-bit code upon exit.  The 8-bit code
indicates possible mismatches or errors.  It is interpreted as a bit string in
which set bits (from left to right) are interpreted as follows:

bit 0 = missing file parameter
bit 1 = unknown or duplicate flag
bit 2 = damaged SCCS file
bit 3 = cannot open file or file not SCCS
bit 4 = SID is invalid
bit 5 = SID does not exist
bit 6 = , -y mismatch
bit 7 = val.1s, -m mismatch

When val processes two or more files on a given command line or multiple
command lines (when reading the standard input), a code is returned that is a
logical OR of the codes generated for each command line and file processed.
val can process up to 50 files on a single command line.  Any number above 50
produces a dump.

FLAGS

Each flag or group of flags applies independently to each named file.  The
flags may appear in any order.

-mname    Compares the value name with the SCCS val.1s identification keyword in
          file.  See "Identification Keywords" for more information on the val.1s
          keyword.

-rSID     Specifies the SID of the file to be validated.  The SID must be valid
          and unambiguous.

-s        Suppresses the error message normally written to standard output.

-ytype    Specifies a type to compare with the SCCS  identification keyword
          in file.  See "Identification Keywords" for more information on the
           keyword.
