Ron, The format is ( to do a LOAD ); LOAD "D1:Filename.BAS" Where D1 is the Disk Drive # ( 1 is the default ) Filename is the filename .BAS means it is a BASIC file format To do a "SAVE" just replace LOAD with SAVE. Hope this helps. Best regards, Steven Ron wrote; I just downloaded an atari 800 emulator for my Ibook. When I have written a basic program how do I save it to floppy? How do I load it again? Directory list? the emulator has 8 diskette drives, how do I specify them in my commands? Any good sites on the Internet with simple stuff like that - I can find basic sites, and Assembly language sites but I don't see anything on DOS sites. Thanks!
