Programming - Corrected procedure MAKE OUT.
First of all, to inform all those who have used
procedure MAKEOUT, that it found
error, that's corrected text of procedure:

By the way sprites can be displayed not
manufacturing procedures vyvoda.Vot, for example,
procedure code deducing two sprites in

Yes, do not get that so you can makarom
display only monochrome images, with
color can do absolutely as well.
Incidentally the same makarom can be arranged
scroller - ie, the text first, fully
appears and then when you click on the button
only changing the address on the virtual
screen. So that scrolling is
oochen quickly. By the way you can build a derivation
with the commands LD and PUSH:
; PROCEDURE FOR WITHDRAWAL Sprite 2X1 2 / 3
