Help with 2.5 Digit 7-Segment LCD Code

[dkw]

The following code was compiled in CCS and counts from 0-9 w/ output to the following LCD (Common Cathode)

https://www.electro-tech-online.com/custompdfs/2013/04/LCD-S2X1C50TR.pdf

This code works but I'm trying to make two modifications:

1) Add a second digit without multiplexing
2) Substitute a 2 or 3 digit variable instead of the counter

The PIC has a built in LCD controller (16F914)

Any help in terms of how this might be coded would be greatly appreciated.

Thanks!
