Re: A83: TASM divide error



I beleive that it is not my routine that is clearing the screen in your 
source, it is a blunder on your part. Here is a section of the source you 
provided in the first mail...

proj_start:
        call _runIndicOff           ; turn off run indic
        ld hl,picture               ; load title pic
        ld de,PLOTSSCREEN 
        ld bc,768 
        ldir 
        call _GRBUFCPY_V            ; copy picture
        call _clrLCDfull            ; clr screen
        SET textEraseBelow, (IY+textflags) ;makes rountine look better
        ld hl, Data_Table_1         ; load data table
        call Text_Select_Menu       ; call TCPA's routine

Now if Im not mistaken, you are LDIRing your picture data to the buffer, 
copying the buffer to the LCD, then clearing the LCD, then calling my 
routine. You may want to exclude that "call _clrLCDfull" command, and it 
should work better. My routine doesnt have any evidence that it wipes out the 
buffer before it places the text. Another thing is it does not write the text 
to the buffer unless you have this command before you call my routine: "SET 
textwrite, (IY+sgrflags)", but then you must be cautious, because my routine 
doesnt copy the buffer after everytime it writes text, so then nothing may be 
apparent. It's then best if you leave that flag I mentioned as being Reset, 
so you dont have to make any alterations to the routine.
