That consumes more memory, it doesn't consume memvars. And yes, I'd call the above #define abuse. *g*

>2. As for runtime execution speed. I don't think that anyone would take that seriously for only a very few performance critical routines. You can of course prove the difference, but how many value has this have in practise

Whether or not it's a "measurable" amount of time depends on how many constant variables are being set up. If the couple of thousand Word constant memvars are all being created. And yes correspondingly huge .h files do take longer to compile, but the enduser doesn't experience that time just us poor slob programmers.

Certainly there are other more time consuming things that go on in our apps.
