 |  Re: Combing Text and freely placeable bitmaps on screen
Well hier my first try and i can't see what i am doing wrong here. (the code is very Beta).
The data is in 0800. I copy 2 lines of 7 chars simultaniously to 2000. (7x11 chars picture).
It draws the first two lines correctly, but when it goes to the second call i get this:
Look here: http://www.patsos.de/plus4/grag5.JPG
10 IF A = 1 THEN 45
20 A = 1 : graphic 4,1: LOAD "grag",8,1
45 REM Char to $2000 from $0800
46 q = 2048 : zi =8192
50 POKE192,((q ) and 255) : POKE193,(((q)/256) and 255) // source 1
60 POKE200,((zi) and 255) : POKE201,(((zi)/256)and 255) //Destination 1
61 q=q+56 : zi = zi + 320
70 POKE169,((q ) and 255) : POKE170,(((q )/256) and 255) // Source 2
80 POKE234,((zi) and 255) : POKE235,(((zi)/256) and 255) // Destination 2
81 q=q+56 : zi = zi + 320
90 REM SETTING UP ADDITIONAL VARIABLE
100 POKE2024,55
120 REM COPYING 56 BYTES FROM CHAR-GEN
130 SYSDEC("DA4F")
140 k = k+1:if k >= 4 then end: else goto 50
run
Side-Effects of the rom-call?
