[comp.os.vms] Sub and detached processes...

LIVINGSTONE%ELMO.DECNet@BERT.CHEM.WISC.EDU (Gonzo Fibes) (05/06/88)

I am using the TPU editor on a microVax II running VMS 4.5.
Supposedly, one is able to spawn to another process using the 
"SPAWN" command.

However, when I do this I receive a "subprocess could not be created"
msg.  I've tried setting the subprocess quota up from 2 to 4, but that 
did not work.  Any ideas?  Is the correct parameter to change the number
of allowable detached processes?  How does a "detached" process differ 
from a "sub" process?

Could it be:          One SPAWNs into a subprocess,
                      but QUEUEs a detached process (eg batch file).

If indeed this is the correct parameter to switch, how do I get at it?
I've hacked all over and can't seem to find a way to change it.

Any comments will be most appreciated.

Thanks.

P.S. - I guess that should have read "Micro VMS".

  Jeff (in response to SPAWNing from TPU),

  I don't know if this will help you out or not but we had a similiar
  problem.  What we discovered was that you could SPAWN out in our own
  directory (SYS$LOGIN) but not anywhere else (without privelage).

  Apparently, there is some temporary file creation activity going on in
  the background... but I haven't followed up on it.  Maybe by changing
  the protection in the directory you want to SPAWN from..??

   Good luck,
