I have seen several programs that use something similar to 

LD   HL, PICTURE             ;HL = Pointer to data
LD   DE, PLOTSSCREEN         ;DE = Pointer to graphmem 
LD   BC, 768                 ;BC = Number of bytes to copy 
LDIR                         ;Copy BC bytes from (HL) to (DE)
CALL _GRBUFCPY_V             ;Copy graphmem to screen

My question is about the format of the data in PICTURE.  I can't seem to 
figure out how to get my picture into the data format used here.  Does 
anybody know how to save a picture created on the 83 into an asm 
program?
