RE: DATA command, did I find a bug or a feature

Hallo Spiro,


>  This application is a recompiled version of the original Commodore 64  binary

I read that but two hours ago it didn't sink in. After reading your mail it did.  In fact that was one of my approaches: a program that translated the 6502 binary into 8088 assembly. But I had at least the sense to combine it with the source of the binary to make it readable:

A_A3DC:
        mov     al,[FacTempStor+1]
;       lda     FacTempStor+1           ; get destination end LB
        sbb     al,[UtilIndex]
;       sbc     UtilIndex               ; subtract MOD(block length/$100) byte
        mov     [FacTempStor+1],al
;       sta     FacTempStor+1           ; save modified new block end LB
        jc      A_A3EC
;       bcs     A_A3EC                  ; branch if no underflow

I wanted to use the result as base of my own BASIC but I soon saw that that was contra-productive. But it was not a waist of time, I can use parts of it as base for my floating point routines.


With kind regards / met vriendelijke groet, Ruud Baltissen
