Synopsis
Official Name: VPutMap
BCALL Address: 455E
Displays a character on screen in the small variable-width font at the current cursor location.
Inputs
- A = TI-ASCII code of character to display
Outputs
Destroys
- A, DE, IX
Comments
This B_CALL outputs the character stored in A at the current cursor location. Unlike its large-font equivalent PutMap, it updates the cursor, and the coordinates are measured in pixels instead of characters and lines.
Example
Shows É in the upper-left hand corner of the screen:
ld a, LcapEAcute ld hl, $0000 ld (penCol),hl B_CALL VPutMap
