Re: A86: Re: reset flag




are you referring to this piece of code? (from rom 1.2)

0d4e  fb        ei
0d4f  cd4502    call    #0245           ;_getcsc
0d52  fdcb09d6  set     2,(iy+#09)
0d56  cd2b3e    call    #3e2b           ;_getkey
0d59  cdcb3d    call    #3dcb           ;_clrScrn
0d5c  fdcb0996  res     2,(iy+#09)
0d60  c3d802    jp      #02d8
