assembly error on DT interrupts

[PCzar3]

Hello Demon,

the two line code snippet is from the interrupt code on this site. Downloads | Book of Interrupts

It is where the variable is defined and yet the assembler complains about it.

I was wondering if anyone else had this happen. It also shows up in the error file.

Thanks,

Paul

For one, there's an order to place the DT includes in your program.

And it would REALLY help to see your complete code.

Hello Demon.

here is the code. It does not show any errors for the main code but the DT interrupts when assembled gives the error code listed above.

CLEAR                       'Clears memoryinclude "codesize.pbp"      'measure the size of the code.
Define Measure 1

and this is the Interrupt code from DT's Interrupts.

The error is for the INTHAND not being defined but, as you can see it is.

Posting snippets is just a waste of time...

Thanks for that enlightening comment Ioannis. If I posted all the code it would be about 4000 lines worth of code. The original question had to do with the assembler complaining about the (INT_ENTRY_H) not being defined. The code snippets are because Demon requested them. They show that the (INT_ENTRY_H) is defined in DT's code. So the only question would be if my includes meet the requirements that Demon was speaking about.

Thanks,
Paul

My first guess is that you have a missing file that it is supposed to be in the same directory as the pbp file.

My second guess is that that PIC doesn't support the Darrel high priority interrupts. I have used a few new chips that don't like the Darrel interrupts. I would try your code with a 18F4550 first to see if it works, and go from there.

Well, we are here to help on specific problems, not guessing what you might have wrong in your listing. If it is 4k long line let it be.

There are many kind people here that will have a second look at your code and surely might find that comma or dot it should or shouldn't be there for you.

If you like guessing work then be it...

Hello Ioannis,
I have worked with Henrik in the past and he has been most helpful. I'll look again at what he has suggested. If I find the solution, I'll post an answer. If not, well I'll have to see what I can find. I don't mean to raise your ire with my problem.
