TROFFTRO{Shift+F}D93.5, 7.0Command and Statement
SCRATCHS{Shift+C} D9 4.x Command and Statement 

 Syntax 
TROFF
 
 Purpose 
Debugging; disable program tracing.

 
 Remarks 
TROFF turns off program tracing; see TRON for details. 
 
Attempting to supply an argument to TROFF will generate SYNTAX ERROR.
 
The NEW command also turns off tracing, presumably to hide the fact that it changes the secret variable Text Pointer to the first line of the (just deleted) program.
 
Example:
10 IF 1 THEN PRINT "TRUE" : ELSE PRINT "FALSE"
TRON : RUN
[10][10]TRUE          first is for IF, nothing for THEN, second is for PRINT
[10]                  this is for ELSE (acts like REM)

READY.
TROFF : RUN
TRUE

READY.
