Amstrad Action TypeChecker & Type-Writer


Anbei das Programm "TypeChecker" von Amstrad Action.
Diese Checksumroutine ist hilfreich beim Abtippen der AA Listings.
Das Pondon von CPCAI folgt in Kürze!

--- End code ---

This (and this) are great, and probably really useful too, but wouldn't they be more suitable for the wiki itself?

Thanks for typing these out!!!

Gryzor: if I hadn't even spoken :D

I remember the original Typewriter program by Pat McDonald being in AA45 because I got interested in typing in the type-ins after discovering this magazine, which began with AA44 (which had the announcement about the Typewriter program). The funny thing about this was I missed the original program in AA45, collected 46,47, could of brought 48, though glad at the time cause it was another Pat's programs which had bugs in it & I generally always missed (or my newsagent did) the Birthday issues which issue 49 was, which ironically enough corrected the mistake (some missing lines) from the program in AA48 and posted the Typewriter program again in that issue (not sure if it was on their B'day Covertape).
By that stage I'd given up on the Typewriter and just typed in the programs and debugged them the old fashion way (line-by-line), though finally after getting AA50, 51, the Xmas Covertape (which was a surprise to me at the time) that came with AA52, had the Typewriter program on it.  And the funny thing was the program had a bug in it or something and it was the bugged version which was on the Covertape.  ;D

I never had any issues with the Pat's Typewriter at the time, though when I got onto the Emulators and ROMs, I noticed this program was very ROM unfriendly, must of been a real pain for people with Real CPCs with their Protext & Maxam ROMs all plugged in. I'm not sure if this was the reason why Simon updated the Type-writer program to TypeChecker.

AA weren't the worst though when it came to providing a program to check your type-ins in though. For the short period I was collecting ACUs their I'd only came across the ACU Proofreader  once and I think in the beginning it was confusing cause the Checksum Codes that program provided looked like they belonged to the program.  ;D
