2737 * call out the the regular perl routines in doio.c which do an
2738 * execvp (for those who really want to try this under VMS).

2746 * Note on command arguments to perl 'exec' and 'system': When handled
2747 * in 'VMSish fashion' (i.e. not after a call to vfork) The args
2748 * are concatenated to form a DCL command string. If the first arg
2749 * begins with '$' (i.e. the perl script had "\$ Type" or some such),
2750 * the the command string is hrnded off to DCL directly. Otherwise,
2751 * the first token of the command is taken as the filespec of an image
2752 * to run. The filespec is expanded using a default type of '.EXE' and
2753 * the process defaults for device, directory, etc., and the resultant
2754 * filespec is invoked using the DCL verb 'MCR', and passed the rest of
2755 * the command string as parameters. This is perhaps a bit compicated,
2756 * but I hope it will form a happy medium between what VMS folks expect
2757 * from lib$spawn and what Unix folks expect from exec.
