Hi,
I do not get any strange printing running your program. I made minor changes but it printed perfectly.
The changes to the yesno were as follows:

1. rename yesno to main (may not be required)

2. removed the second read events and added clear events.

3. changed yesnorpt to the following:
set console off
SET DEVICE TO PRINTer && this redirects the @ says to printer

FOR I=1 TO 5 NEXT && and apparently the prior forms
@ I,10 SAY 'HELLO' && colors go with it.
@ I,20 SAY 'THERE'
NEXT
EJECT
set printer to && most likely required because I'm on NT
SET DEVICE TO SCREEN
set console on

* end of YESNORPT.prg

4. changed menu to say "do yesnorpt" from "do yesnorpt.prg"

Don't no what to tell you?
