If your display supports transparent text set bc to -1. If not using other optional parameters you still need a coma to show where they belong. Eg TEXT x, y, string$ , , , , , -1
The catch is when you change the text it will be on top of the old text so the total number of characters needs to be the same by adding leading or trailing spaces to equal the longest line. eg
txt1$ = "Hello World" txt2$ = " Earth "
This works for VGA mode 1 but for colour modes you will need to save an image of the area where the text is going to be (before running the program perhaps) with:- SAVE IMAGE file$, x, y, w, h and load that image before changing the text.
