NAME
       File::Spec::VMS - methods for VMS file specs

SYNOPSIS
        require File::Spec::VMS; # Done internally by File::Spec if needed


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

       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 specifica-
           tion, in order to avoid juxtaposing two VMS-syntax
           directories when MM[SK] is run.  Also expands expres-
           sions 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 direc-
           tory in the current default directory, and returns a
           directory or file specification accordingly.

       Methods always loaded


       canonpath (override)
           Removes redundant portions of file specifications
           according to VMS syntax.

       catdir
           Concatenates a list of file specifications, and
           returns the result as a VMS-syntax directory specifi-
           cation.  No check is made for "impossible" cases (e.g.
           elements other than the first being absolute file-
           specs).

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

       curdir (override)
           Returns a string representation of the current direc-
           tory: '[]'

       devnull (override)
           Returns a string representation of the null device:
           '_NLA0:'

       rootdir (override)
           Returns a string representation of the root directory:
           'SYS$DISK:[000000]'

       tmpdir (override)
           Returns a string representation of the first writable
           directory from the following list or '' if none are
           writable:

               sys$scratch:
               $ENV{TMPDIR}


       updir (override)
           Returns a string representation of the parent direc-
           tory: '[-]'

       case_tolerant (override)
           VMS file specification syntax is case-tolerant.

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

       file_name_is_absolute (override)
           Checks for VMS directory spec as well as Unix separa-
           tors.

       splitpath (override)
           Splits using VMS syntax.

       splitdir (override)
           Split dirspec using VMS syntax.

       catpath (override)
           Construct a complete filespec using VMS syntax

       abs2rel (override)
           Use VMS syntax when converting filespecs.

       rel2abs (override)
           Use VMS syntax when converting filespecs.
