DISCLAIMER: I don't have the GS/OS reference, so if the information I'm
looking for is in that, please tell me and I'll go and try to
find it.
I am trying to write a program launcher, using Orca/C 1.1. I got it to the
point that it would run the other program, but when the second program quits
the machine crashes. I am launching it with a QuitGS call, flags=0, and
the pathname set to the full pathname of the next program. I have shut down
all the tools except for SANE, Tool Locator, Memory Manager, and the Loader,
because Orca/C apprently doesn't let you shut those down from the program (they
are started up and shut down automagically)
Any help would be muchly appreciated. d:-)

If there's any way you can let ORCA/C transfer control to the program for you, that would be much cleaner--in other words, hopefully they provided access to the flags and pathname parameters in the QuitGS call that will happen when your program exits, so that you can control which program runs next. If this doesn't help, send me BINSCIIed object code & I can at least tell you why it crashes. -- David A. Lyons, Apple Computer, Inc. | DAL Systems Apple II Developer Technical Support | P.O.
