Hello Darrel,
Is there any way i can implement you instant interrupt routines on PICs which do not have the TMR0 interrupt ( like the PIC16C54A) ???

No,
The 16C54A doesn't have any interrupts.
They only have 512 words of program space, 25 bytes of RAM, and a 2-level hardware stack.
At 4 dollars each, I can't imagine why anyone would ever use them.

Same observation for 16F84(a)

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Yeah, no kidding.
Everyone uses those F84's for examples, probably because there's nothing else to confuse you like, USARTs, CCP's, A/D's or SSP's. But man, who'd actually want to use one.
I've had 2 of them for a couple years. But they're still Virgins. Never been plugged into anything.

Could it simply be that a lot of the information on the net for PIC newbies is for projects using the 16C84 and for simple programmers that program them.
I certainly started with the 16C84 but I wouldnt use one now. For small stuff I use the 16F628 on my existing projects and 16F88 on the new projects because of the bootloader.
Larger projects are using the 16F877 or 18F452 again with bootloaders.
Somewhere I have some 508's including a couple of JW's that were bought and never used along with a UV eraser that has never even ben plugged in and probably never will now !!!!
As far as I am concerned, Flash + Bootloader + PBP + MCS rules
