Hi Keith,

the ugly part was not to use more or less efficient code.
I meant only, that fixed numbers are used inside the code, was ugly.

On any case, if it was possible, that the number can be different on reusing the code, then only symbolic names should be used.

And any allocation of memory space was definitively a case, on which the value can change.


A bit of topic, but mostly its unwise to push
and pop every register. Mostly the more compact code was generated, if registers used as local variables or for parameter
passing to functions.
And it was the callers task to save a register if its value was really needed later.

Only interrupts must save anything.
