This brings up a followup question: on a microVMS system with a limited number of users (for example a two-user licence) and with a large number of terminal ports, I start a whole bunch of subprocesses using SPAWN/NOWAIT/IN=TTxx/OUT=TTxx SPAWN/NOWAIT/IN=TTyy/OUT=TTyy SPAWN/NOWAIT/IN=TTzz/OUT=TTzz. Se, as long as the master process doesn't log out (which can be prevented) I have four people working on four terminals with only a two-user licence. Disadvantage: the other processes don't have LOGINs, so security is pretty bad, but that may be okay for many applications. Question: is that possible (I don't see why not), and if the answer is yes, is it against my licence agreement ? Disclaimer: I don't have a microVAX and we have an unlimited regular VMS licence. I am just hacking around, us usual.
