After a little more thought, I realize that although this (using '#!/usr/bin/vax' )
will work for basic legacy simh scripts, several of the new simh command features
won't work (i.e. GOTO, Conditional trapping via ON, SHIFT, etc.). The issue here
is that when a simulator is invoked this way, commands are coming from stdin
and not a simh command file which does support these other commands.
On some platforms (some legacy BSD environments) there was a bug which
could leave a simulator spinning uselessly if the invoking script didn't execute
an exit command. This is now fixed.
