c64 guru: save a file again

This is a "feature" of Commodore DOS (the error is 63, FILE EXISTS, 00, 00). You can handle this in two ways. 1. Save-with-replace: SAVE"@0:PROGRAM",8 This has a notorious bug on 1541 disk drives that tends to strike when the disk is very near capacity, since both copies of the program must exist on the disk at once. A safer approach is to 2. Scratch first, save later. OPEN15,8,15,"S0:PROGRAM":CLOSE15 SAVE"PROGRAM",8 This is the safest approach as it has the least chance to go berserk unseen. Many disk wedges like Epyx FastLoad and DOS WEDGE 5.1 reduce the OPEN statement to @S0:PROGRAM or >S0:PROGRAM or some such variant. Alternatively, have a block in your program like this: 63998 END 63999 OPEN15,8,15,"S0:PROGRAM":CLOSE15:SAVE"PROGRAM",8 then RUN 63999 whenever you want to save-and-replace. -- ---------------------------------- personal: http://www.armory.com/~spectre/ -- Cameron Kaiser, Floodgap Systems Ltd * So.
