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