GRAPHIC —Select a graphic mode
1) GRAPHIC mode [,[clear][,s]]
2) GRAPHIC CLR
This statement puts the Commodore 128 in one of the six graphic
modes:
mode description
0 40-column text
1 standard bit-map graphics
2 standard bit-map graphics (split screen)
3 multicolor bit-map graphics
4 multicolor bit-map graphics (split screen)
5 80-column text
The clear parameter specifies whether the bit mapped screen is
cleared (equal to 1) or left intact (equal to 0). The S parameter indi
cates the starting line number of the split screen when in graphic
mode 2 or 4 (multicolor or standard bit map split screen modes). The
default starting line number of the split screen is 19. Lines are num
bered 0-24.
When executed, GRAPHIC 1-4 allocates a 9K-bit mapped area. The
start of BASIC text area is moved above the bit-map area, and any
BASIC program is automatically relocated. This area remains allo
cated even if the user returns to TEXT mode (GRAPHIC 0). If the
clear option is specified as 1, the screen is cleared. The GRAPHIC
CLR command deallocates the 9k, bit-mapped area, and relocates
any BASIC text.
EXAMPLES:
GRAPHIC 1,1
GRAPHIC 4,0,10
