Hi,

The WTR is for write protect of some all all of the EEPROM, the " _ENABLE_ON " is not a valid option.
You would normally use _OFF as you normally want to write to all EEprom.

Full details of the options are given in the MPASM/Includes/16f877a.inc file.

You will also find your register names d_a,b &c are invalid, just change them to something else.

Your code has very few comments to clearly show what ports and pins are being use for the hardware, eg lcd, its also such a lot of code, again without comments it means trying to go though it all is not easy.

If you can suply a ciruit diagram / pinout I could try it in a simulator to see how it runs

Edit

You might also find this good tutorial of help with these examples on the Usart and LCD

http://www.winpicprog.co.uk/pic_tutorial7.htm download and see the code examples and see #7.7 which is the hardware Usart for the 876/877 chips.
