How to delete the last line of a txt file

[Squashman]

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.

avoids trailing space

Code: [Select]

set model=blablabla
0>nul set /p=%model%>mdchk.txt


cool, thanks
