Hello Jay,

I had a run in Macsbug for you.
As you already know, I have no skill in asm but I tested some code and it seems
that there is no difference in the code generated by the compiler. It's just a
matter of moving a byte in some register. The only difference is from where the
byte is taken. so, no subroutine here.
I tried a variant of my test where the var you called given$ was global or not.
When given$ was not set as a global it gave two instructions more with
PEEK(@given$).
I used to think in the same way as you do, changing some code expecting a speed
improvement.
Well I must go back to work after this testing.
Of course, this must be approved by some guru.

See you.
