Some days ago I posted a question about errors that occur while trying to
run non-DJGPP-programs from inside bash.

> All of the programs that you say don't work are non-DJGPP programs.

Yes, DJGPP-programs run OK

I also noticed, that I can call any program from inside bash like this :
c:>c:/command.com /c nc.exe
But it should be a blame, that bash is not able to load&execute simple dos
executables!

I cut away all stuff that can not interfere with programs

Its a week or so ago, that I posted my question, so here again a snippet
from my message

2.) My configuration on the beginning
    OpenDOS 7.02 - should be the same as NovellDOS 7
    Stacker 4 (e:/stacvol.dsk maps to c:)
    DJGPP 2.01 bash 1.14.7

and the error messages I got

Thank you in advance
