I am not saying you should read directly from the environmental variable in your program. I am saying pass it as a COMMAND line argument. This has nothing to do with a graphical interface. If your program was setup correctly to read a variable from input you COULD call your program from your batch file like so.

MSL.exe %model%

I haven't programmed in C++ since I TOOK my class in 1996 so I really can't recall how to do it but just about every Compiled and Interpreted programming Language can accept command line input in some fasion.Quote from: Salmon Trout on June 13, 2012, 12:36:25 PM

avoids trailing space

Code: [Select]set model=blablabla
0>nul set /p=%model%>mdchk.txt
