Thanks, Michael. Nicely analyzed.

I think you and I are almost identical. Over the years I have written=20
some beautiful and elegant
PIC code for the mid-range PIC (PIC16F/PIC12F) and stored each module.=20
So, in essence,
I HAVE a higher-level language. But the PIC16F1939 has some significant=20
differences, such
that I'd have to rewrite and retest almost all of my "library". That=20
task will be a significant one.

So, knowing this, I simply wanted to VERIFY that all that work had been=20
done on JALv2. 'cause
if it hadn't, then it would be faster to code in MPASM. Its that simple.=20
I didn't want a war, just
a verification.
