It is part of an assembly language program written for the Microchip PIC16F628 processor and coded to work with their MPLAB assembler program.
It is not complete and even the small section you show has some strange code in it.

Changing the code is easy. Just look at the very end of the program and you can see the letters are stored by their ASCII numbers in decimal. Use an ASCII character table to find the numbers for the new letters and substitute them after the RETLW instruction. For example, to change 'A' to 'T' you change 'RETLW 65' to RETLW '84'. Just make sure there is a 'RETLW 0' at the end of the new word, it is used to tell the program thee are no more characters to display.
To recreate the HEX file you need an assembler. Microchip currently have two free assemblers you can download but for this program I suggest you use the older MPLAB version rather than MPLABX. You can find it (version 8.91) at this web page: **broken link removed** near the bottom of the page. It's a big file I'm afraid.
Install it on your computer then use it to load and open your file, edit the words, then press F10 to assemble a new HEX file. The instructions in the program are very good.
Brian.
The program was written a long time ago (16F628 is now obsolete) so MPLAB 8.0 should work. The latest 8.91 version is better though.
