NAME
       ExtUtils::MM_VMS - methods to override UN*X behaviour in
       ExtUtils::MakeMaker

SYNOPSIS
        use ExtUtils::MM_VMS; # Done internally by ExtUtils::MakeMaker if needed


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

       Methods always loaded


       eliminate_macros
            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.

       fixpath
            Catchall routine to clean up problem MM[SK]/Make
            macros.  Expands macros in any directory
            specification, in order to avoid juxtaposing 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.

            If optional second argument has a TRUE value, then
            the return string is a VMS-syntax directory
            specification, if it is FALSE, the return string is a
            VMS-syntax file specification, and if it is not
            specified, fixpath() checks to see whether it matches
            the name of a directory in the current default
            directory, and returns a directory or file
            specification accordingly.

       catdir
            Concatenates a list of file specifications, and
            returns the result as a VMS-syntax directory
            specification.

       catfile
            Concatenates a list of file specifications, and
            returns the result as a VMS-syntax directory
            specification.

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

       curdir (override)
            Returns a string representing of the current
            directory.

       rootdir (override)
            Returns a string representing of the root directory.

       updir (override)
            Returns a string representing of the parent
            directory.

       SelfLoaded methods

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

       guess_name (override)
            Try to determine name of extension being built.  We
            begin with the name of the current directory.  Since
            VMS filenames are case-insensitive, 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.

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

       path (override)
            Translate logical name DCL$PATH as a searchlist,
            rather than trying to split string value of
            $ENV{'PATH'}.

       maybe_command (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.

       maybe_command_in_dirs (override)
            Uses DCL argument quoting on test command line.

       perl_script (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.

       file_name_is_absolute (override)
            Checks for VMS directory spec as well as Unix
            separators.

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

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

       constants (override)
            Fixes up numerous file and directory macros to insure
            VMS syntax regardless of input syntax.  Also adds a
            few VMS-specific macros and makes lists of files
            comma-separated.

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

       const_cccmd (override)
            Adds directives to point C preprocessor to the right
            place when handling #include <sys/foo.h> directives.
            Also constructs CC command line a bit differently
            than MM_Unix method.

       pm_to_blib (override)
            DCL still accepts a maximum of 255 characters on a
            command line, so we write the (potentially) long list
            of file names to a temp file, then persuade Perl to
            read it instead of the command line to find args.

       tool_autosplit (override)
            Use VMS-style quoting on command line.

       tool_sxubpp (override)
            Use VMS-style quoting on xsubpp command line.

       xsubpp_version (override)
            Test xsubpp exit status according to VMS rules ($sts
            & 1 ==> good) rather than Unix rules ($sts == 0 ==>
            good).

       tools_other (override)
            Adds a few MM[SK] macros, and shortens some the
            installatin commands, in order to stay under DCL's

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

       dist (override)
            Provide VMSish defaults for some values, then hand
            off to default MM_Unix method.

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

       xs_c (override)
            Use MM[SK] macros.

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

       top_targets (override)
            Use VMS quoting on command line for Version_check.

       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.

       dynamic_lib (override)
            Use VMS Link command.

       dynamic_bs (override)
            Use VMS-style quoting on Mkbootstrap command line.

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

       manifypods (override)
            Use VMS-style quoting on command line, and VMS
            logical name to specify fallback location at build
            time if we can't find pod2man.

       processPL (override)
            Use VMS-style quoting on command line.

       installbin (override)
            Stay under DCL's 255 character command line limit
            once again by splitting potentially long list of
            files across multiple lines in realclean target.

ExtUtils::MM_VMS(Perl Programmers Reference GExtUtils::MM_VMS(3p)


       subdir_x (override)
            Use VMS commands to change default directory.

       clean (override)
            Split potentially long list of files across multiple
            commands (in order to stay under the magic command
            line limit).  Also use MM[SK] commands for handling
            subdirectories.

       realclean (override)
            Guess what we're working around?  Also, use MM[SK]
            for subdirectories.

       dist_basics (override)
            Use VMS-style quoting on command line.

       dist_core (override)
            Syntax for invoking VMS_Share differs from that for
            Unix shar, so shdist target actions are VMS-specific.

       dist_dir (override)
            Use VMS-style quoting on command line.

       dist_test (override)
            Use VMS commands to change default directory, and use
            VMS-style quoting on command line.

       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 MM_Unix method
            call catfile repeatedly.  Also, if we have to rebuild
            Config.pm, use MM[SK] to do it.

       makefile (override)
            Use VMS commands and quoting.

       test (override)
            Use VMS commands for handling subdirectories.

       test_via_harness (override)
            Use VMS-style quoting on command line.

       test_via_script (override)
            Use VMS-style quoting on command line.

       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.
