1413 ** fileify_dirspec() - convert a directory spec into the name of the

1415 ** The style (VMS or Unix) of the result is the same as the style
1416 ** of the parameter passed in.
1417 ** pathify_dirspec() - convert a directory spec into a path (i.e.
1418 ** what you prepend to a filename to indicate what directory it's in).
1419 ** The style (VMS or Unix) of the result is the same as the style
1420 ** of the parameter passed in.
1421 ** tounixpath() - convert a directory spec into a Unix-style path.
1422 ** tovmspath() - convert a directory spec into a VMS-style path.
1423 ** tounixspec() - convert any file spec into a Unix-style file spec.
1424 ** tovmsspec() - convert any file spec into a VMS-style spec.

3302 * Note on command arguments to perl 'exec' and 'system': When handled
3303 * in 'VMSish fashion' (i.e. not after a call to vfork) The args
3304 * are concatenated to form a DCL command string. If the first arg
3305 * begins with '$' (i.e. the perl script had "\$ Type" or some such),
3306 * the the command string is handed off to DCL directly. Otherwise,
3307 * the first token of the command is taken as the filespec of an image
3308 * to run. The filespec is expanded using a default type of '.EXE' and
3309 * the process defaults for device, directory, etc., and if found, the resultant
3310 * filespec is invoked using the DCL verb 'MCR', and passed the rest of
3311 * the command string as parameters. This is perhaps a bit complicated,
3312 * but I hope it will form a happy medium between what VMS folks expect
3313 * from lib$spawn and what Unix folks expect from exec.
