RPL equivalents to BREAK, CYCLE, EXIT, etc.?

Error traps are a way for loops where you can't access the index easily, but you can exit FOR loops without generating an error condition.
Just set the index to the end value, and you're done;-)

Consider the following loop, which will run 100 times:

Code:

<< 1 100
   FOR x
     x DISP
   NEXT
>>

To break out of such a loop, you simply have to set the exit condition to TRUE.
The following code will exit the loop after 50 times:

Code:

<< 1 100
   FOR x
     x DISP
     IF x 50 ==
     THEN 100 'x' STO
     END
   NEXT

The principle is the same for DO..UNTIL and WHILE..REPEAT loops, of course.
