NP - Nosy Prompter
by Russell Nelson
The program is copyrighted but freely copyable using the Free
Software Foundation's General Public License. That means that anyone
you give it to can give it to someone else, and they must be able to
get the source. The license is widely available, usually called
COPYING. Contact me if you can't find a copy.
Have you ever shelled to DOS from an application program only to forget
that you had done so, and you ran your application again? This can
result in a lack of memory to run the application, or if you have shelled
from an editor, you can lose changes to a file, or if you have shelled
from a communications package, you can lose your session and even be forced
to reboot.
I've done it myself. I've done it enough times to do something about
it by writing NP, the Nosy Prompter. NP will peek around in your memory
to find suspended programs, and it will remind you of them at every
DOS prompt. NP is written in assembly language, and only takes 900 bytes
when resident. Source is included and the program is freely copyable.
Unfortunately, in order to find the name of the program, NP requires
DOS 4.x. Versions of DOS prior to 4.x didn't save the name of the program
in the memory control blocks where NP looks for it.
Bugs, enhancements, kudos to:
