Yes, that is one of my programs. The silly thing is that the 'Format' option doesn't even work as I forgot to include it - and it would have been plagiarised anyway as I didn't know Z80 assembler back then!
It's been dated to 1992 when you were 12 and 3/4, though I can't workout which Format Routine it was using, though it's been setup to accept one which can format Vendor or Data and has an origin of &8000, I thought it might of been the QuickFormat from AA73 Oct 1991, but that resides at &4000 and uses a RSX to format the Discs.
I remember being really proud of myself when some of my programs were published (I was 14 years old at the time), but I think I had written some better ones at the time. I sent AA a few dozen programs and let them select the 'best' ones.
Issue 106 & 107 according to
CPC-POWER Archives and in Issue 108 they passed the remark about no more Disk Organisers in a guide to submitting Type-Ins, sadly that was the last issue with Readers Type-Ins in them.
