  • I'd still be interested in also having test and set versions of all those test and jumps.

    DJZ/DJNZ and TJZ/TJNZ are complementary and have the same last letter.
    DJU/DJNU and TJF/TJNF are complementary and have different last letters, which makes no sense. U for underflow is plain wrong here anyway as decrementing from $8000_0000 causes an underflow, not from zero. I like F for Full or $FFFF_FFFF or F's and DJU/DJNU should be renamed DJF/DJNF.

    You're right!

    I'll rename DJU/DJNU to DJF/DJNF.

    Thanks, Chip. I think that was my final comment on DJx/IJX/TJx.

  • Thanks for pointing that out. I should have realized, myself. That was ugly.
  • Ugly with a capital U! :)
