I am currently working on a project which uses the 2E interrupt when
spawning processes. However, a nasty glitch has reared its ugly head; it
seems that if a batch file invokes an executable on anything but its last
line, and the executable uses INT 2E to spawn a process, DOS merrily
ignores the command line passes in DS:SI and instead continues processing
the next line of the batch file.
E.G.: given this batch file:
ECHO Before...
MASTER.EXE
ECHO After...
if MASTER.EXE attempts to use INT 2E, instead of whatever it may
have passed, the "ECHO After..." line will execute. When MASTER terminates,
this line does not get executed again.
If anybody has a workaround that will convince DOS not to resume batch file
processing, I would be most verily grateful for your help.

My understanding is that anything you can do with it, you can do more normally just by EXECing a copy of COMMAND.COM. It's more bother though; what is appealing about 2E is how easy it is to use. But as with most things, its worth about what you paid for it.
