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

[DSMan195276]

FWIW I don't really think this is an optimization thing, unless Pete turned the "Compile program with C++ optimization flag" thing on then the code isn't being optimized. Beyond that, both the SCREEN() and ASC() functions live in a separate

.o

file from the main code so typically this means they would never be inlined since the linker doesn't normally do that (and we don't tell it to do link-time-optimization).

The one thing I was wondering is whether

h

was a SINGLE rather than integer value, then there would be a floating point conversion going on. Still, I would expect calling

func_screen()

to be slower than the floating point conversion.

The other consideration is whether the event checking around

h = SCREEN(j,  k + i)

adds too much overhead, simply because

func_screen()

and

func_asc()

do almost nothing in these cases and thus should be very fast. If you have a chance you might try putting

$CHECKING:OFF

around it and see if the speed discrepancy is still there.
