out of rom,the segment or the program is too large Main".

In CCS, a function can't be larger than a ROM page. For the 16F877,
a ROM page is 2048 words. The solution is to break up the code in
main() and put some of it into functions. Then call those functions from
main(). This will allow the compiler to put those functions into other
ROM segments, and you won't get the "out of rom" error anymore.
Example:
Code:

void func1(void)
{
// code
}

void func2(void)
{
// code
}

//====================
void main(void)
{
// Initial main code goes here.

// Put some of the main() code into these functions.
func1();
func2();
// or more.

// Other main code goes here.

while(1);
}

There have been several posts regarding this error. Do a search on 'out of rom' and you should find the answers you are looking for.

also you must add #separate before the main function
