They do introduce the concepts of programming, so they do help a lot. (I started off on Scratch)
Anyway, try these commands:
PRINT "[text here]"
This puts [text here] onto the screen.
LOCATE 2,5
This makes the next PRINT show at x coordinate 2, y coordinate 5 (the text screen is 50x30).
CLS
This clears the screen of all text and resets LOCATE.
