Here's a handy program for anyone with a plotter: it generates patterns and gives you the option of sending it to a Tandy plotter. Paul Bridal is the man to thank for the code. If you have a different brand of plotter, a breakdown of the codes may help you to write your own. - CHR$(17) Sets text mode.
- CHR$(18) Sets graphics mode.
- S1 Gives 40 columns.
- P Lets you mix text and graphics.
- M Means move pen.
- I Sets the origin.
- D Means draw.
- A To return to text mode.
Below is a demo of one of the pictures you can create. This dump was performed on a TP-40 plotter.
