Yes to all of that Steve.
All the calibrations are set the same on the PIC. The program is different, but the sound has changed between them.
The only thing I can think of is that the timing is off for some reason between the programs, but in such a way that it isn't obvious as to what is doing it.
I have been considering using those other routines to make the beep, but this has become one of those things that needs an explaination now to satisfy me.
I also found that table that Melanie made while I was searching for possible explainations.
I think today I am going to redo the program from a different angle and see if while doing that I uncover the reason. There has to be a logical reason for it.

After using a different method to get what I wanted I managed to eliminate 200 words which I always like, and bring the two programs to within 66 words of each other. There was no difference in the sound. The second, longer, program still has different sound from the same command as the shorter program. I'm really scratching my head here although I've learned more thinking outside the box through it all.
