     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  keyletter  arguments, 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 keyletter arguments are defined as follows.  The effects
	  of  any keyletter argument 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 %M% keyword in file.

	       -ytype	      The argument value type is compared with
			      the SCCS %Y% 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 keyletter argument;
	       bit 2 = corrupted SCCS file;
	       bit 3 = cannot 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 val can process two	 or  more  files  on  a	 given
	  command  line and in turn 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.

     BUGS
	  Val can process up to 50 files on  a	single	command	 line.
	  Any number above 50 will produce a fatal error.
