UP DOWN Counter PIC16F84A

Hello, I just want to ask how to set the limit of this up down counter to something I desired(e.g 0-150 instead of 0-999)
I do not own the code but simply using it to understand how it works for future works. I am using Proteus to simulate and test the program
Program Code:
Start
LSB EQU H'0021'
MSB EQU H'0022'
NUM1 EQU H'0023'
NUM2 EQU H'0024'
NUM3 EQU H'0025'
NUM4 EQU H'0026'
NUM5 EQU H'0027'
VALUE EQU H'0028'
ONE EQU H'0029'
TENS EQU H'002A'
HUNDRED EQU H'002B'

FIGURE EQU...
