Equation For Specific Line Length Needed

[OldMoses]

Starting on line 725:
                IF drag < 1 AND drag2 < 1 THEN
                    _DELAY 1
                    town = 1
                    GOTO start:
                END IF


A couple of observations:

I did a search for drag2 and this is the only instance of it. drag2 will always be zero.
This IF...END IF block is within another one testing if drag < 1 {line 718} and is probably redundant.
Given that it is shunting the program flow back to 'start', could it be possible that it is jumping
around the _DISPLAY on line 734? Your program may not be locking up, but is rather stuck in a loop
where _DISPLAY is set and not being refreshed. Perhaps because drag is remaining below 1... not sure

I placed an _AUTODISPLAY after the 'start' on line 80, and played a lot farther, fighting a 300 power dragon.
Then the screen locked again.
