Name
       val - validate SCCS file

Syntax
       val -
       val [-s] [-rSID] [-mname] [-ytype] files

Description
       The  command  determines  if the specified file is an SCCS file meeting the characteristics specified by the optional argument list.  Argu-
       ments to may appear in any order.  The arguments consist of keyletter arguments that begin with a ``-'' and named files.

       The command 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.

       The  command  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.

Options
       The effects of any keyletter argument apply independently to each named file on the command line.  The keyletter arguments are  defined	as
       follows:

	      -  Causes stdin to be read until end of file.

	      -s Suppresses all error messages.

	      -rSID
		 Indicates  specified  delta  version  number.	A check is made to determine if the SID is ambiguous, for example, r1 is ambiguous
		 because it physically does not exist but implies 1.1, 1.2, and so forth, which may exist) or invalid, for example, 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
		 Compares specified value with the SCCS val.1 keyword.

	      -ytype
		 Compares specified type with SCCS  keyword.

       The 8-bit code returned by is a disjunction of the possible errors.  It can be interpreted as a bit string where set bits  are  interpreted
       (from left to right) as:

	      bit 0 = missing file argument
	      bit 1 = unknown or duplicate keyletter argument
	      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%, -y mismatch
	      bit 7 = %M%, -m mismatch

       Note that can process two or more files on a given command line and can process multiple command lines 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.

Restrictions
       The command can process up to 50 files on a single command line.  Any number above 50 produces a core dump.

Diagnostics
       Use for explanations.
