Hi, I'm really stumped here =( I'm trying to run "Start /wait prog.exe /q" in WinNT4 dos. /q makes the prog.exe 'quiet', not needing any user interface and not openning any windows. The prog.exe does everything it should but when executing "echo %errorlevel%" at the end, the result is 45. What is Errorlevel 45?! I've tried searching around but can't find anything. Please help if you can. Thanks!

**I THINK** that's a value returned by the last aplication used. In general cases: errorlevel=0 means there where no errors, errorlevel=1 means there where errors ie: if you do in a batch file: find "abc" text.dat> nul Find.exe will return an errorlevel=1 if it doesn't find anything. If it can find the "abc", it will return a errorlevel=0 ie2: in choice.com: choice /c:abc Choose If user chooses option "a", choice.com wil return errorlevel=1. If "b", errorlevel=2 and so. Then you can make the batch act depending on users choice, like this: if errorlevel=3 echo C if errorlevel=2 if not errorlevel=3 echo B if not errorlevel=2 echo A (not that in batch, a string "if errorlevel=#" returns a true value if the errorlevel is equal OR GREATER then #) But a program may return several errorlevels. I have no idea what does errorlevel being 45 means on your case I hope I have helped someway -- Secret_Doom --
