NAME
     changes - Run filemerge on two versions of an sccs file

SYNOPSIS
     changes [-iaw] file

DESCRIPTION
     This program invokes filemerge to compare two versions of  a
     file  under  sccs  control.   If neither option -i nor -a is
     specified, the program picks what appear to be the two  most
     recent  versions.   That is, if the file is checked out, the
     current version is compared to the  latest  delta.   If  the
     file is not checked out, the latest two deltas are compared.

     If -i (interactive) is specified, some recent delta  commen-
     tary  is  displayed and the user is prompted for the old and
     new versions, which default as described above.   Option  -a
     (all) is similar, except that all of the delta commentary is
     shown, using a pager such as "more".

     Ordinarily filemerge is invoked in read-only  mode.   Option
     -w  (write) causes filemerge to be invoked normally, so that
     the files can be merged.

ENVIRONMENT
     The environment variable PAGER is  used  as  the  executable
     through which to pipe sccs prt output if option -a is speci-
     fied.  If PAGER is not set, "more" is used.
