npp_save
cd "$(CURRENT_DIRECTORY)"
g++ "$(FILE_NAME)" -o "$(NAME_PART)"
npp_run cmd.exe /k "$(NAME_PART)"

For compiling cobol, you would use your cobol compiler rather than “g++”, and would have to format the command line appropriately; if your compiler is not in your path, you will have to do something like “c:\full\path\to\compileCobol.exe”.

If you don’t want to also run the program when compiled, then you could just remove the “npp_run …” command from the NppExec script.

I would use npp_exec plugin in order to achieve this but you can use the standard Run menu as well, depends how flexible you want to be.
