When I display text on the screen with;
CENTER TEXT 320, 240, "Once upon a time ..."

The text flickers.

Is likely an issue with with sync or cls, would need to see more of your code around your main loop

sometimes people come back to dbp years later ….. .... (and for those who did not know applications made with it seem to work ok on win 10)
anyway, questions are what this forum is for so let us begin:

@statichash

Sorry for the two year pause there. I have been battling throat cancer and just recently recovered well enough to continue exploring game programming.
Anyway, I still have the screen flicker problem with Dark Basic. Below is the code that does it.
Set window on
Set window layout 1,1,1
Set Window title "Hello World"
Set window position 100,200
Set window size 640,480
Print "Hello, World!"
wait key

If I take out all of the Set lines, the screen doesn't flicker at all. Why is it doing that when I use the Set commands on the window?
Do I need some other code here to prevent that from happening?
Thanks

Doesn't flicker at all on my side therefore I cannot tell the difference but try this:

Set window on
Set window layout 1,1,1
Set Window title "Hello World"
Set window position 100,200
Set window size 640,480
do
Print "Hello, World!"
wait key
sync
loop

This is how it was solved. Thanks to Bored of the Rings and Scorpyo for their input.

sync on
sync rate 30
sync
Set window on
Set window layout 1,1,1
Set window title "Hello World"
Set window position 100, 200
Set window size 640,480
Set text size 60

do
Print "Hello, World!"
sync
wait key

loop

Yeah right..my bad, sync was meant to be before "wait key"
Glad it helped.
