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.

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

I was looking through the *.inc files..
I dont see it for the 18F2445 also i looked atthe chip I know most 16F88 and could not find it either ! I am not familiar with the INC files. What are they used for ?.

I do not find it on Microchips web site either. Do you mean another chip? 2455?I dont see it for the 18F2445
The 2455 is in PBPs current version, I do not remember when it was added.
The 16F88 is there. If Micro Code has it then it is in the PBP directory.
That is where the configuration bits are set.I am not familiar with the INC files. What are they used for ?.
One other thing about the 18Fs. You hace to use MPASM for the assembler. PM will not work.
