YAP-II programmer

[Martin Baker]

Hello,
Has anyone here built the YAP-II from "Programming and customizing PIC
Microcontrollers, Second Edition"?
Specifically, I bough a board from Dontronics and wouold like to burn
the YAP-II.asm into my 16C711. I have another simple programmer that
will do the Job, but I can't get MPASM to recognize the .asm and
compile it to hex. Does anyone have any suggestions to what silly
thing I am doing wrong?

thanks in advance.
A beginner.
