Here is something might help might not
[start of program]
print "hello world"
[end of program]
that does only the printing of "hello world" it has nothing to suspend it after that.
[start of program]
print "hello world"
wait key
[end of program]
This will wait for user input before exiting.
[start of program]
Do
print "hello world"
loop
[end of program]
This is an infinite loop. It will continually repeat the code between do and loop until broken by the user or an exit command. With the print command every time you use it the cursor is moved down one line. So this will fill the entire left side of the screen with "hello world"
Hope that helps. if not catch me on rgt or there are plenty of smart people here.
