Hi,
I'm new to simh and have a problem I'm hoping someone may help with.
Could someone tell me the purpose of the assert pc =7465 and det mta4 in
the job stream?
I am using i7094 simulator to compile and run a fortran II and fap
program. I run the ibsys.txt script and see no errors but the simulator
hangs following a HALT instruction after the programs are compiled and
executed.
I assume this HALT is a result of the $STOP command?
The system hangs after the HALT and does not respond to ctl-C or ctl=D
or anything else. However, if I start another terminal and run some
other test it sometimes awakens the terminal and simh continues. I see
this problem with example tests from sky-vision.com also.
What could cause this to hang?
1. Here is the tail end of the input job stream; When the program
executes it simply prints the data following the * DATA card. The
program does seem to be running as I expect. I've eliminated some blank
lines to condense this a little.

2. Here is the tail end of the system output on sysou1.bcd showing the
text output from execution;

3. And here is the tail end of the LO from sysou1.bcd

4. and, finally here is the do_ibsys.txt file used to create the
input stream;
