It always helps to post the code you have so we can check it out and point out what you're doing wrong. You can highlight the code and press the "code" button to put it in a code snippet like this:
rem setup screen
sync on
sync rate 60
backdrop on
color backdrop 0
hides mouse
rem start of main loop
do
rem print some text
center text 320,240,"Ponies are awesome"
rem refresh screen
sync
rem end of main loop
loop
We are really happy to help out, don't get me wrong, but we just can't do it if you don't supply us with anything...
