When running Tasmanian Traders, environment.set, at some point

IF !DEBUMODE
SET ESCAPE OFF
ELSE
SET ESCAPE ON
ENDIF

executes perfectly.

I figured this was an ok thing to do and used the same approach, but lo and behold, the thing bombed with a Variable DEBUGMODE not found.

No amount of tracing and debugging the TT app reveals where the heck
debugmode is set, in fact TT does not know about it either but does not seem to be bothered by it.
The help file never heard of debugmode either.

Am I missing something here, or maybe rather, what am I missing ?
