ERRNO.COM
SETS ERRORLEVEL FROM COMMAND LINE ARGUMENT
MS QUICKC V. 2.5
Tiny Memory Model (.COM file)
DAN GOLDBERG, 10/90


This little program simply sets errorlevels (exit codes).
Just type the errorlevel you want, from 0 to 255, on the
command line, and ERRNO will set that errorlevel.

Or type ERRNO by itself, and you will be prompted for an
errorlevel value. The ONLY values accepted are 0 - 255.


example:
ERRNO 254 (will set errorlevel to 254)

(or type ERRNO alone to be prompted for errorlevel)

to test, type:
if errorlevel 255 cls (will NOT clearscreen)

then type:
if errorlevel 254 cls (will clear screen)
if errorlevel 253 cls (will clear screnn)
. . .

I need not tell anyone out there how important errorlevels are
when working in DOS, especially with batch files.

If you use the program, please send one dollar, or just a hello,
