Hi!

I've spent all weekend reading....
(>400 pages)

Q1. DISABLE

See PicBasic Pro manual.
DISABLE and ENABLE are pseudo-ops in that they give the compiler
directions, rather than actually generate code.


Q2. 14/15 interrupts.

Open the data sheet of the 16f877 and search the word 'interrupt'.

Read section 8 of the Mid-Range MCU Family Reference Manual.

AN566 - Using the PORTB Interrupt on Change as an External Interrupt.
