Code:

21 ...
22 X≤Y?
23 GTO 25
24 ...     <= this line is executed if X>Y, else it is skipped
25 ...     program continues here

Gene: And the beauty of this (IMO) is that on a line-addressing model with limited steps, it is VERY efficient. No step burned with a LBL.

Of course... that's only true until you have to modify the program and then it really hurts.

Or if you have a ton of memory! :-)
