I am trying to compile the code and above message shows up. What I don't understand is
Code:

  Seg 00800-00FFF, 0610 left, need 00972
  Seg 01000-017FF, 0800 left, need 00972
  Seg 01800-01FFF, 0800 left, need 00972
  Seg 00000-00002, 0000 left, need 00972
  Seg 00003-00003, 0001 left, need 00972
  Seg 00004-0001D, 0000 left, need 00972
  Seg 0001E-007FF, 01E2 left, need 00972


what does left means? Does it mean that space is 610 but need 972 size? Does it mean that code to be written is 972 in size but there is no segment in memory which accept that ?

Any help would be greatly appreciated.

Yes, it means the space available in that segment is 610 words, but
your function requires 972 words.

The solution is to break up your large function into two or more smaller
functions. Then the compiler can fit them into the available space.

Another possible option is to use a similar PIC but with more memory.

You don't say which PIC you've chosen,but there is always a 'bigger,better' one coming out tomorrow !! Usually for less money too.

One thing that causes Out of Rom errors is if you have too much code in one function, including main(). The PIC's memory space is like a book. You have several pages in the book but your code(function) has to fit on each page and cannot carry over to the next page. Try breaking your program into smaller functions that can be called individually and have the same effect.
