ankit.tayal560 - type `start /?` in a windows command prompt for more information on what marto is trying to impart. basically there are 3 ways to start new processes in perl: open - `open (IN, "program.exe\|") or die "couldn't start program.exe"` system - `system('program.exe')` backticks or qx - `qx(program.exe)` or `program.exe` careful what you do when running programs that require external input from users, but in a nutshell what's happinging in `system('start "" "' . $calc . '"');` is the same as `system('program.exe arg1');` Cheers, Shadowsong	[reply] [d/l] [select]
