SLOW or SLOW 0 sets low res mode
SLOW 1 to SLOW 6: Sets high-res mode, and additionally sets the
high-res print mode as follows:
SLOW 1: Print as normal, but with inverse video characters.
SLOW 2: Print as normal
SLOW 3: Print at PLOT position, with text foreground in white.
SLOW 4: Print at PLOT position, with text foreground in black.
SLOW 5: Print at PLOT position, with text background inverted.
SLOW 6: Print at PLOT position, with text foreground inverted.
CLS 0 clears the low res display
CLS 1 clears the high res display to black
CLS 2 clears the high res display to white
CLS 3 inverts the high res display
CLS 1 and CLS 2 also reset the PLOT position to 0,0 at the bottom
left corner of the screen (see section 4 for an explanation of
these terms).
COPY copies the lo-res display to the ZX printer.
COPY 0 copies the lo-res display to the ZX printer.
COPY 1 copies the hi-res display to the ZX printer.
| 1: | Draw a line to absolute co-ordinates, in white. |
| 2: | Draw a line to absolute co-ordinates, in black. |
| 3: | Draw a line to absolute co-ordinates, inverting. |
| 4: | As 3, but omit last point. |
| 5-8: | As 1-4, but use relative co-ordinates |
| 33-40: | As 1 to 8, but with coarse dotted line |
| 65-72: | As 1 to 8, but with fine dotted line |
| 97-104: | As 1 to 8, but with chain dotted line |
| 9-16: |
As 1-8, but plot a single pixel Note that PLOT 12 and PLOT 16 miss out the pixel, so simply move the PLOT position. |
| 41-48: | As 1-8, but draw and fill triangle between the current and previous two PLOT positions. |
| 73-80: | As 41 - 48, but fill with texture (not available in invert mode) |
