When you look at the disassembled code, does it have the correct opcode?
That's the bottom line.

The MPASM help file says the syntax is:

retfie s

where the default is s is 0, and 1 for fast

naturally, the 4550 include file contains this:  FAST EQU 1

I don't think there's ever a comma between the op-code and the first
argument; only to separate multiple arguments.

I think you're okay, just another minor datasheet blip.
