NAME
       ExtUtils::MMVMS - methods to override UN*X behaviour in ExtU-
       tils::MakeMaker

SYNOPSIS
         Do not use this directly.
         Instead, use ExtUtils::MM and it will figure out which MM*
         class to use for you.

DESCRIPTION
       See ExtUtils::MMUnix for a documentation of the methods provided
       there. This package overrides the implementation of these methods, not
       the semantics.

       Methods always loaded

       wraplist
           Converts a list into a string wrapped at approximately 80 columns.

       Methods
       Those methods which override default MMUnix methods are marked "(over-
       ride)", while methods unique to MMVMS are marked "(specific)".  For
       overridden methods, documentation is limited to an explanation of why
       this method overrides the MMUnix method; see the ExtUtils::MMUnix
       documentation for more details.

       guessname (override)
           Try to determine name of extension being built.  We begin with the
           name of the current directory.  Since VMS filenames are case-insen-
           sitive, however, we look for a .pm file whose name matches that of
           the current directory (presumably the 'main' .pm file for this
           extension), and try to find a "package" statement from which to
           obtain the Mixed::Case package name.

       findperl (override)
           Use VMS file specification syntax and CLI commands to find and
           invoke Perl images.

       maybecommand (override)
           Follows VMS naming conventions for executable files.  If the name
           passed in doesn't exactly match an executable file, appends .Exe
           (or equivalent) to check for executable image, and .Com to check
           for DCL procedure.  If this fails, checks directories in DCL$PATH
           and finally Sys$System: for an executable file having the name
           specified, with or without the .Exe-equivalent suffix.

       pasthru (override)
           VMS has $(MMSQUALIFIERS) which is a listing of all the original
           command line options.  This is used in every invokation of make in
           the VMS Makefile so PASTHRU should not be necessary.  Using PASTHRU
           tends to blow commands past the 256 character limit.

       pmtoblib (override)
           VMS wants a dot in every file so we can't have one called
           'pmtoblib', it becomes 'pmtoblib.' and MMS/K isn't smart enough
           to know that when you have a target called 'pmtoblib' it should
           look for 'pmtoblib.'.

           So in VMS its pmtoblib.ts.

       perlscript (override)
           If name passed in doesn't specify a readable file, appends .com or
           .pl and tries again, since it's customary to have file types on all
           files under VMS.

       replacemanpageseparator
           Use as separator a character which is legal in a VMS-syntax file
           name.

       initDEST
           (override) Because of the difficulty concatenating VMS filepaths we
           must pre-expand the DEST* variables.

       initDIRFILESEP
           No seperator between a directory path and a filename on VMS.

       initmain (override)
       initothers (override)
           Provide VMS-specific forms of various utility commands, then hand
           off to the default MMUnix method.

           DEVNULL should probably be overriden with something.

           Also changes EQUALIZETIMESTAMP to set revision date of target file
           to one second later than source file, since MMK interprets pre-
           cisely equal revision dates for a source and target file as a sign
           that the target needs to be updated.

       initplatform (override)
           Add PERLVMS, MMVMSREVISION and MMVMSVERSION.

           MMVMSREVISION is for backwards compatibility before MMVMS had a
           $VERSION.

       platformconstants
       initVERSION (override)
           Override the *DEFINEVERSION macros with VMS semantics.  Translate
           the MAKEMAKER filepath to VMS style.

       constants (override)
           Fixes up numerous file and directory macros to insure VMS syntax
           regardless of input syntax.  Also makes lists of files comma-sepa-
           rated.

       specialtargets
           Clear the default .SUFFIXES and put in our own list.

       cflags (override)
           Bypass shell script and produce qualifiers for CC directly (but
           warn user if a shell script for this extension exists).  Fold mul-
           tiple /Defines into one, since some C compilers pay attention to
           only one instance of this qualifier on the command line.

       constcccmd (override)
           Adds directives to point C preprocessor to the right place when
           handling #include  directives.  Also constructs CC com-
           mand line a bit differently than MMUnix method.

       toolsother (override)
           Throw in some dubious extra macros for Makefile args.

           Also keep around the old $(SAY) macro in case somebody's using it.

       initdist (override)
           VMSish defaults for some values.

             macro         description                     default

             ZIPFLAGS      flags to pass to ZIP            -Vu

             COMPRESS      compression command to          gzip
                           use for tarfiles
             SUFFIX        suffix to put on                -gz
                           compressed files

             SHAR          shar command to use             vmsshare

             DISTDEFAULT  default target to use to        tardist
                           create a distribution

             DISTVNAME     Use VERSIONSYM instead of      $(DISTNAME)-$(VERSIONSYM)
                           VERSION for the name

       co (override)
           Use VMS syntax on command line.  In particular, $(DEFINE) and
           $(PERLINC) have been pulled into $(CCCMD).  Also use MM[SK]
           macros.

       xsc (override)
           Use MM[SK] macros.

       xso (override)
           Use MM[SK] macros, and VMS command line for C compiler.

       dlsyms (override)
           Create VMS linker options files specifying universal symbols for
           this extension's shareable image, and listing other shareable
           images or libraries to which it should be linked.

       dynamiclib (override)
           Use VMS Link command.

       staticlib (override)
           Use VMS commands to manipulate object library.

       extracleanfiles
           Clean up some OS specific files.  Plus the temp file used to
           shorten a lot of commands.

       zipfiletarget
       tarfiletarget
       shdisttarget
           Syntax for invoking shar, tar and zip differs from that for Unix.

       install (override)
           Work around DCL's 255 character limit several times,and use VMS-
           style command line quoting in a few cases.

       perldepend (override)
           Use VMS-style syntax for files; it's cheaper to just do it directly
           here than to have the MMUnix method call "catfile" repeatedly.
           Also, if we have to rebuild Config.pm, use MM[SK] to do it.

       makeaperl (override)
           Undertake to build a new set of Perl images using VMS commands.
           Since VMS does dynamic loading, it's not necessary to statically
           link each extension into the Perl image, so this isn't the normal
           build path.  Consequently, it hasn't really been tested, and may
           well be incomplete.

       nicetext (override)
           Insure that colons marking targets are preceded by space, in order
           to distinguish the target delimiter from a colon appearing as part
           of a filespec.

       prefixify (override)
           prefixifying on VMS is simple.  Each should simply be:

               perlroot:[some.dir]

           which can just be converted to:

               volume:[your.prefix.some.dir]

           otherwise you get the default layout.

           In effect, your search prefix is ignored and $Config{vmsprefix} is
           used instead.

       cd
       oneliner
       eecchhoo
           perl trips up on "" thinking it's an input redirect.  So we
           use the native Write command instead.  Besides, its faster.

       quoteliteral
       escapenewlines
       maxexeclen
           256 characters.

       initlinker
       eliminatemacros
           Expands MM[KS]/Make macros in a text string, using the contents of
           identically named elements of %$self, and returns the result as a
           file specification in Unix syntax.

           NOTE:  This is the canonical version of the method.  The version in
           File::Spec::VMS is deprecated.

       fixpath
              my $path = $mm->fixpath($path);
              my $path = $mm->fixpath($path, $isdir);

           Catchall routine to clean up problem MM[SK]/Make macros.  Expands
           macros in any directory specification, in order to avoid juxtapos-
           ing two VMS-syntax directories when MM[SK] is run.  Also expands
           expressions which are all macro, so that we can tell how long the
           expansion is, and avoid overrunning DCL's command buffer when
           MM[KS] is running.

           fixpath() checks to see whether the result matches the name of a
           directory in the current default directory and returns a directory
           or file specification accordingly.  $isdir can be set to true to
           force fixpath() to consider the path to be a directory or false to
           force it to be a file.

           NOTE:  This is the canonical version of the method.  The version in
           File::Spec::VMS is deprecated.

       osflavor
           VMS is VMS.
