Anyway you like!
By default, pressing Esc generates an error (error code 17) which will abort your program, or can be trapped using ON ERROR or ON ERROR LOCAL in the usual way (but note the caveat when using PRIVATE).
Alternatively you can issue the *ESC OFF command, in which case Esc behaves like a regular key, and can be read using INKEY or GET (key code 27).
Lastly, you can detect (asynchronously) when the Esc key is depressed using INKEY(-113).

Thanks, the "*ESC OFF " was what I needed. The othe info may come in handy later.

How do you write 'ESC OFF'? What is the entire command you need to write?

It's a 'star command', simply prefix it with an asterisk:
Code:
If you prefer you can use OSCLI, but there's little benefit in this case:
Code:
