How do I make a ProDOS disk that will boot and start a BASIC program?
If you want ProDOS to boot and start a BASIC program, then both PRODOS and BASIC.SYSTEM must be present. (BASIC.SYSTEM should be the first .SYSTEM file on the diskette.) The “hello” program on a ProDOS diskette is named “STARTUP”. This is the program which will be run upon booting the diskette. (If there is no “STARTUP” program, you will end up at the usual BASIC prompt after booting.) A simple STARTUP program you can type in and save to your new ProDOS diskette is … 10 TEXT: HOME 20 PRINT CHR$(4)”CAT” 30 END After typing in the program, just enter SAVE STARTUP. Next time you boot the diskette, the above program will run and the diskette’s CATALOG will be displayed. A good ready-made STARTUP program and program selector for launching ProDOS 8 programs on a IIgs is available as speedgs.shk. The file unShrinks to the Startup program and a Readme directions file. To get speedgs.shk from the net, see Csa21MAIN4: Get It- Links to popular software packages.
