Or not use "for loop" when you need "while" or "repeat until" instead... :-)

It is not advised (AND bad programming practice) to change the value of the looping variable in the for-loop. So better do like kine says.

Never said anything about changing the variable. Pretty sure we agree that for loops are rarely used in NAV.

True, they are very rarely used.

But how do you want to make the to-statement true? Or you let it finish or you change the looping-variable in the loop.

It's an easy decision really. Use FOR when you know exactly how many times you are going to loop. Use REPEAT UNTIL or WHILE when you don't know how many times. REPEAT if you have to loop at least once, WHILE if you don't.

I cheat on that though, I like using UNTIL, in case I ever need to add an evaluation.
