Are you using a demo version ? Older demo versions had a ROM
limitiation of only 2K. This is 1/4 of the normal ROM space. That could
explain your problem. |

Maybe 200 lines of output_c, output_b and delay_ms have created a function bigger than a segment (800h). Maybe splitting a big function into multiple smaller ones will help?

"Please what is meant by seg 00004 - 07E8 Left, need 07F1 for example. "
This means that the compiler needs 0X07F1 for a particular block of code (function).
The biggest available block it can find is in segment (or page) 4 and it is only 0X07E8 in size, so the compiler can't fit it in ROM
What you need to do is break up that 07F1 piece of code into smaller pieces so the compiler can better fit them into the pages of ROM.
No single function can bridge two pages, but many small functions can fit on a single page.
Check out the "separate" directive. Sometimes if a function is only called once the compiler optimizer will put the function inline
and it can no longer go on a separate ROM page from the calling function.

The 16F series has the issue with memory pages that don't exist in the 18F
series. That's the reason the 18F compiled successfully. That's also why I
switched to all 18F PICs in my projects. Take a look at the datasheets under
memory organization...
