     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.

     Diagnostics
	  Use help(CP) for explanations.

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