Fix for flashing text

I'm not sure this is a very helpful resource, other than being a quick fix (theres a better quick fix too...) Things you might want to consider: Why does the text flash? Why use WAIT over something like VSYNC? Does the screen actually have to be cleared for your use case?

I think the biggest question you should ask yourself is "why am I printing static text in a loop?"

VSYNC is better

Ideally you would do: WHILE 1 LOCATE 1,1:PRINT "blah blah stuff i'm typing blah blah" WEND

When you do want to clear the screen, you should do it right BEFORE displaying, not after, as in

WHILE TRUE
VSYNC 1
CLS
Print "blah blah stuff i'm typing blah blah"
WEND

To add to what Lumage is saying: You want to have a pretty picture on screen before you start doing calculations that might take a while. That way the player has something to look at.
