This is odd because I have programs that call subroutines at the very end of
a 2K PIC from the ISR routine at ORG 4 with no trouble.  I don't save PCLATH
and never adjust it in the program.  The only trouble I run into is when I
do a computed GOTO jump, in which case I set the PCLATH manually.

If your statement is true, I'd never be able to return to nearly 80% of my
calls, since they run the gamut of program memory locations from 0x00A
through 0x700.  Yet I have no problems.
