3248 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |

a0d0e21e LW |
3252 | * the first token of the command is taken as the filespec of an image |
3253 | * to run. The filespec is expanded using a default type of '.EXE' and | |
3eeba6fb | 3254 | * the process defaults for device, directory, etc., and if found, the resultant |
a0d0e21e | 3255 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
3eeba6fb | 3256 | * the command string as parameters. This is perhaps a bit complicated, |
a0d0e21e LW |
