FB Win32 and SCREEN() function.

[MystikShadows]

Ok I set my screen mode with:

Code:

SCREEN 21, 8, 8, 1

And I print something on the screen with a regular print statement.

Code:

DIM TempScreen(80,25)
CLS
PRINT "THIS IS A TEST"
PRINT "THIS IS ANOTHER TEST"
PRINT "THIS IS A TEST OF TESTS"

I loop through the screen to store the screen contents:

Code:

FOR OuterCounter = 1 to 30
    FOR InnerCounter = 1 to 4
        TempScreen(OuterCounter, InnerCounter) = SCREEN(InnerCounter, OuterCounter, 0)
    NEXT InnerCounter
NEXT OuterCounter

I replace the existing text with new text. with LOCATE 1,1 and a couple of print statements


Then I loop back to restore the screen contents.

Code:

FOR OuterCounter = 1 to 30
    FOR InnerCounter = 1 to 4
        LOCATE InnerCounter, OuterCounter
        PRINT TempScreen(OuterCounter, InnerCounter)
    NEXT InnerCounter
NEXT OuterCounter

This techniques works fine in SCREEN 0, but as soon as I try a graphics mode of any type, it fails, it reports no errors, but blanks are printed instead of the character that are supposed to be there.

What's wrong with this?

Simple: the SCREEN() function only works in text mode... Should really sit down and modify this so it works also in gfx mode...

damn...yeah I agree...it should be changed, a character is a character after all....and I'd sure need it....:-)...
