How cool and how simple... but this is very strange. I can't imagine
what "MZP" is about [or why the poster thinks that that's what the OS is
looking for]:
C:\DOCUME~1\Bernie>type donothing.exe
FOO
C:\DOCUME~1\Bernie>donothing.exe
C:\DOCUME~1\Bernie>echo ABC>donothing.exe
C:\DOCUME~1\Bernie>donothing.exe
C:\DOCUME~1\Bernie>type donothing.exe
ABC
BUT: if I do
echo xyz>donothing.exe
and I try to execute it, I get a popup with:
command Prompt - donothing.exe
The NTVDM CPU has encountered an illegal isntruction
....
However, just
echo AA >donothing.exe
and
echo A >donothing.exe
Both work just fine.
trange... :o) But cute...
MZ is the "magic number" for windows executables, found in the first 2 bytes
of the file. It must be followed by another character, thus the MZP that the
poster provided, could be MZ followed by any character. This file then fools
windows into thinking it is executable and does nothing.
