666 | ** of the parameter passed in. |

2118 | * |
2119 | * vms_do_aexec() and vms_do_exec() are called in response to the |
2120 | * perl 'exec' function. If this follows a vfork call, then they |
2121 | * call out the the regular perl routines in doio.c which do an |
2122 | * execvp (for those who really want to try this under VMS). |
2123 | * Otherwise, they do exactly what the perl docs say exec should |
2124 | * do - terminate the current script and invoke a new command |
2125 | * (See below for notes on command syntax.) |
2126 | * |
2127 | * do_aspawn() and do_spawn() implement the VMS side of the perl |
2128 | * 'system' function. |
2129 | * |
2130 | * Note on command arguments to perl 'exec' and 'system': When handled |
2131 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args |
2132 | * are concatenated to form a DCL command string. If the first arg |
2133 | * begins with '$' (i.e. the perl script had "\$ Type" or some such), |
2134 | * the the command string is hrnded off to DCL directly. Otherwise, |
2135 | * the first token of the command is taken as the filespec of an image |
2136 | * to run. The filespec is expanded using a default type of '.EXE' and |
2137 | * the process defaults for device, directory, etc., and the resultant |
2138 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
2139 | * the command string as parameters. This is perhaps a bit compicated, |
2140 | * but I hope it will form a happy medium between what VMS folks expect |
2141 | * from lib$spawn and what Unix folks expect from exec. |
