I didn't know Galleon supplied that batch file.

It's to be used in the same way as the error batch file. Open a Basic program and compile it from QB64. Then run the batch file straight afterwards, it will recompile the C++ that QB64 generated but without the debugging symbols. It will create an executable called no_syms.exe which does the same thing as the original, but the file is smaller.
