  Different result than expected when poking to screen
Posted by: emook - 2016-12-10, 10:31 PM - Forum: ZX Basic Compiler - Replies (5)

Hello,

In normal basic we can do this following code :

Code:
10 BORDER 0: PAPER 0: INK 6: CLS
20 FOR i=1 TO 7
30 FOR y=0 TO 21
40 FOR x=0 TO 31
50 LET l=22528+x+y*32
60 POKE l,8*i
70 NEXT x
80 NEXT y
90 NEXT i

[Image: tK1VcJ5.png]

To fill the screen with the desired colour (I know this example seems pointless, but the same method to poke a screen char is used quite a bit for me)

however, in ZXB it only seems to pokes to the top third of the screen :

Code:
border 0
paper 0
ink 6
cls

dim i as ubyte
dim x as ubyte
dim y as ubyte
dim l as uinteger

FOR i=1 TO 6
FOR y=0 TO 23
FOR x=0 TO 31
l=22528+x+y*32
POKE l,8*i
NEXT
NEXT
NEXT

Anyone know what I am doing wrong here?

Thanks!

Some IM music playback. Music converted with Autosirli from the mastersystem into Vortex Tracker, then some INS and OUTS.

Some IM music converted from the MS using AutoSirli and Vortextracker. Code could be massively optimised!

EDIT
