You'd think this would be faster, but NO!!!!!! [Resolved]

[DSMan195276]

Hi Matt,

I've already modified the code to the SELECT CASE snippet I posted, which solved the slow down the h = SCREEN() created. I do have a backup copy of the one with the speed killing situation. No, $CHECKING:OFF does nothing to offset the decreased speed issue in the backup copy with the speed reduction problem.

h, btw is an integer, defined by a DEFINT H-K at the top of the program.

Thanks for trying I'll have to give it some more thinking. Unfortunately on my machine just putting that logic into a loop (with some dummy types to make it compile) comes out with it running slightly faster if you store the value in

h

rather than use

SCREEN()

three times (as you originally assumed would be the case).

I'm not sure this is what you're doing, but I would note that the usage of

h

gets more expensive if it's in a

SUB

or

FUNCTION

and you're constantly calling it - there's some allocation overhead that goes on for

h

every time you enter the

SUB

or

FUNCTION

it is declared in. This is also a notable difference from

SELECT CASE

, as the internal variable that stores the value you're selecting on (to do the comparisons with each

CASE

) does not get allocated the same way and thus does not have that overhead. None of my testing on this can get close to a 5x slowdown though
