Yes, Anna. I just pasted the source code into a .BAS file, then used BAS2BIN.EXE and BIN2WAV.EXE to make the .BIN and then the .WAV files, and then loaded it successfully with LOAD.

(Note that, when the program automatically runs after loading, some PRINT comands don't work... [Yet another MC-1000 BUG! smile ] Stop the program with CTRL+C and then RUN it again.)

Why, are you having any trouble?
