This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
The next line is a means of formatting a printout so that it will be printed in columns, so many items long then a second column will start from the top again but shifted right. Then comes a line, IF INKEY(-99) REPEAT:u%=u%+1:SOUND&11,-4,d%(f%),(u%/4):UNTIL NOT INKEY(-99):PRINTTAB(x,y);(u%DIV4);" ";d%(f%) INKEY(-99) will wait for the SPACE BAR to be pressed. So long as it is pressed a REPEAT UNTIL loop will cycle. This loop is nested within the first REPEAT UNTIL loop. 1 will be added to u% and the SOUND command will play the note defined by the pitch stored in the array box d%(f%). Since this is the first cycle the pitch value will be stored in box d%(1). The duration of this note will be 1/4 as defined by (u%/4).If the SPACE BAR is still pressed u% will = 2 and the note will continue. For as long as the SPACE BAR is pressed the note will continue playing, each time 1 will be added to u%. When the SPACE BAR is released the note will stop. The accumulated value of u% will be divided by 4, without a remainder, and printed beside the value of d%(1), ie the note which was played. This accumulated value of u% divided by 4 will also be put into the array t% which stores the values of the duration of each note and which originally had all of its values set to 6. The next line will check if e%=f%, if it does not the loop will cycle back to the first REPEAT. 1 will be added to f% making the next note to be played d%(2), u% will be reset back to 0 and the program will wait for the SPACE BAR to be pressed again. When e%=f% ie when all of the notes composed have been edited the procedure will finish and jump to PROCmenu. Here you have the option to repeat the editing procedure, playback the tune with the new values for duration or to reenter the compose section and re-do the tune from scratch. And that is all there is to it. If anyone can improve on any aspects of this program then please do and send it in. I originally wrote this program and text for EUG33 but held it back so that I could sort out the bugs. All except the one in PROCedit(e%) have been sorted. Some minor alterations have been made to the program but the text is still relevant. If I try to rewrite the text now I might be here forever.
