2707 ** fileify_dirspec() - convert a directory spec into the name of the
2708 ** directory file (i.e. what you can stat() to see if it's a dir).
2709 ** The style (VMS or Unix) of the result is the same as the style
2710 ** of the parameter passed in.
2711 ** pathify_dirspec() - convert a directory spec into a path (i.e.
2712 ** what you prepend to a filename to indicate what directory it's in).
2713 ** The style (VMS or Unix) of the result is the same as the style
2714 ** of the parameter passed in.
2715 ** tounixpath() - convert a directory spec into a Unix-style path.
2716 ** tovmspath() - convert a directory spec into a VMS-style path.
2717 ** tounixspec() - convert any file spec into a Unix-style file spec.
2718 ** tovmsspec() - convert any file spec into a VMS-style spec.

4617 * in 'VMSish fashion' (i.e. not after a call to vfork) The args
4618 * are concatenated to form a DCL command string. If the first arg

4620 * the the command string is handed off to DCL directly. Otherwise,
4621 * the first token of the command is taken as the filespec of an image
4622 * to run. The filespec is expanded using a default type of '.EXE' and
4623 * the process defaults for device, directory, etc., and if found, the resultant
4624 * filespec is invoked using the DCL verb 'MCR', and passed the rest of
4625 * the command string as parameters. This is perhaps a bit complicated,
