FreeBASIC started as a compiler for QuickBASIC, the successor of GW-BASIC. QuickBASIC can run most GW-BASIC programs as is. As the FreeBASIC dialect has evolved since then, you'll have to use the -lang qb switch when compiling QuickBASIC or GW-BASIC source code.

Awesome, thanks for the info!

Hello, Thank you very much for your help, I was able to compile my 3000 lines script, some minor problems with input and on error but I fixed it, it compiled perfect like Quick basic because I wrote script in Msx Basic, it's running great only when compiled screen is deferent maybe because pc basic interface is diferent from windows , I don't know. Thanks Rob & Marc R
