     DELTA(CP)		      XENIX System V		     DELTA(CP)

     Name
	  delta - Makes a delta (change) to an SCCS file.

     Syntax
	  delta [-rSID] [-s] [-n] [-glist] [-m[mrlist]] [-y[comment]]
	  [-p] files

     Description
	  delta is used to permanently introduce into the named SCCS
	  file changes that were made to the file retrieved by get(CP)
	  (called the g-file, or generated file).

	  delta makes a delta to each SCCS file named by files.	 If a
	  directory is named, delta behaves as though each file in the
	  directory were specified as a named file, except that
	  nonSCCS files (last component of the pathname does not begin
	  with s.) and unreadable files are silently ignored.  If a
	  name of - is given, the standard input is read (see
	  Warning); each line of the standard input is taken to be the
	  name of an SCCS file to be processed.

	  delta may issue prompts on the standard output depending
	  upon certain options specified and flags (see admin(CP))
	  that may be present in the SCCS file (see -m and -y options
	  below).

	  Options apply independently to each named file.

	  -rSID		 Uniquely identifies which delta is to be made
			 to the SCCS file.  The use of this keyletter
			 is necessary only if two or more versions of
			 the same SCCS file have been retrieved for
			 editing (get -e) by the same person (login
			 name).	 The SID value specified with the -r
			 keyletter can be either the SID specified on
			 the get command line or the SID to be made as
			 reported by the get command (see get(CP)).  A
			 diagnostic results if the specified SID is
			 ambiguous, or if it is necessary and omitted
			 on the command line.

	  -s		 Suppresses the issue, on the standard output,
			 of the created delta's SID, as well as the
			 number of lines inserted, deleted and
			 unchanged in the SCCS file.

	  -n		 Specifies retention of the edited g-file
			 (normally removed at completion of delta
			 processing).

	  -glist	 Specifies a list (see get(CP) for the
			 definition of list) of deltas which are to be
			 ignored when the file is accessed at the
			 change level (SID) created by this delta.

	  -m[mrlist]	 If the SCCS file has the v flag set (see
			 admin(CP)) then a Modification Request (MR)
			 number must be supplied as the reason for
			 creating the new delta.

			 If -m is not used and the standard input is a
			 terminal, the prompt MRs? is issued on the
			 standard output before the standard input is
			 read; if the standard input is not a
			 terminal, no prompt is issued.	 The MRs?
			 prompt always precedes the comments? prompt
			 (see -y keyletter).

			 MRs in a list are separated by blanks and/or
			 tab characters.  An unescaped newline
			 character terminates the MR list.

			 Note that if the v flag has a value (see
			 admin(CP)), it is taken to be the name of a
			 program (or shell procedure) which will
			 validate the correctness of the MR numbers.
			 If a nonzero exit status is returned from MR
			 number validation program, delta terminates
			 (it is assumed that the MR numbers were not
			 all valid).

	  -y[comment]	 Arbitrary text used to describe the reason
			 for making the delta.	A null string is
			 considered a valid comment.

			 If -y is not specified and the standard input
			 is a terminal, the prompt comments? is issued
			 on the standard output before the standard
			 input is read; if the standard input is not a
			 terminal, no prompt is issued.	 An unescaped
			 newline character terminates the comment
			 text.

	  -p		 Causes delta to print (on the standard
			 output) the SCCS file differences before and
			 after the delta is applied.  Differences are
			 displayed in a diff(C) format.

     Files
	  All files of the form ?-file are explained in Chapter 3,
	  ``SCCS: A Source Code Control System" in the XENIX
	  Programmer's Guide.  The naming convention for these files

	  is also described there.

	  g-file	   Existed before the execution of delta;
			   removed after completion of delta.

	  p-file	   Existed before the execution of delta; may
			   exist after completion of delta.

	  q-file	   Created during the execution of delta;
			   removed after completion of delta.

	  x-file	   Created during the execution of delta;
			   renamed to SCCS file after completion of
			   delta.

	  z-file	   Created during the execution of delta;
			   removed during the execution of delta.

	  d-file	   Created during the execution of delta;
			   removed after completion of delta.

	  /usr/bin/bdiff   Program to compute differences between the
			   ``retrieved'' file and the g-file.

     Warning
	  Lines beginning with an SOH ASCII character (binary 001)
	  cannot be placed in the SCCS file unless the SOH is escaped.
	  This character has special meaning to SCCS (see sccsfile(F))
	  and will cause an error.

	  A get of many SCCS files, followed by a delta of those
	  files, should be avoided when the get generates a large
	  amount of data.  Instead, multiple get/delta sequences
	  should be used.

	  If the standard input (-) is specified on the delta command
	  line, the -m (if necessary) and -y options must also be
	  present.  Omission of these options causes an error to
	  occur.
