    Default Memory Overflow? Urgently need advice

    Hi guys, Im getting the message[306] crossing page boundary problem..

    Im using a pic16F88 and it has a total amount of 9777+ asembly lines

    Ive been googling and it seems that means that my pic16F88 has not sufficient memory to hold the program, however I feel like the program is very simple and straight forward.

    So Im here looking for advice on ways to make the program fit onto my pic or should i get an 18X series. The code is approximately 257 lines but please give me an advice or two if possible! It will be greatly appreciated!

    The main issue - without codeReset program, theres no memory overflow; with codeReset program it overflows

    Code:
    DEFINE OSC 8
OSCCON.4 = 1 'Sets the internal oscillator frequency to 8 MHz
OSCCON.5 = 1
OSCCON.6 = 1

    'Turns off analog to digital conversion. Refer to
                'Threaded Design Example A.4 p.296-299 of the textbook
                 'for an example of how to configure and use A/D conversion

    Check the front section of your PBP manual for Code Crosses Page Boundary Messages for an explanation.

    Also, in your PBP directory there is a file that lists all the posible error codes. I'm writing this post using my cellphone, so I can't tell you the name of the file.

    PM.TXT is the file name.

    Thanks alot Bruce!

    I looked at the section, and that means it is not a memory overflow, just that certain codes were written in another page.

    But in the PBPro compiler, how do I find out where the "1st page" it was written in ends? PBP only has line numbers and therefore I wasnt able to figure out at which point in the code the program flipped to the next "page"

    The compiler generates a .LST file. Open this and scroll down to 800h. You can see which code section crosses the page boundary.
