Ok I found it, exceeded the memory of the chip
I used the 16f877a, but now I am getting errors that it do not recognize, the INTRC_OSC, CCPMX_ON, MCLR_ON mode......

Hello again,
If you open up the file P16F877A.inc found in the microchip\mpasm.suite you will find (all / only) the configs that work for that chip, as well as every possible register. Every PIC has such a file there.
The error is just saying that that config is unsupported.

I am thinking of using the PIC16F2455 because it has a lot more memory, and I am running out of it on the pic16F88. I never used the PIB18 series, is it the to program or is it much harder ? I am going a project for a christmas gift, I dont have time to learn a new technology.
Keep track of your gosub / return and gotos so you do not get stack overflow or underflows a return should only be approached from a gosub and gosub should always be terminated with return. You should not make word vars unless you actually need them, so as to save memory space. When you post a project, you will make it far easier to debug if you include ALL the code including the setup code, configs and variables. If you do not need IF/THEN/ELSE/ENDIF use a simple IF/THEN
one liner to save memory.
18F chips MAY require a programmer upgrade, I found my JDM did not work and had to buy PICKit2.

Hi well i will post the full 500 line program tomorrow.
As for the programmer I use the Olimex programmer with usb connection. works great with the 16F series says it works with the 18F too but never tried it. just wandering if the programming if the ports is much di8fferent..

Working with the 18Fs is not really any different than the 16Fs.
The 18Fs have many more options so sometimes the configs are a little more difficult, but the default setup in the PBP *.inc file is good to get started.
The benefits make running the 18Fs worth it in many cases.

Always wear safety glasses while programming.
I think I will go aheah and get started with the 18F series. I will see what happens then programming it.
