[How to use S/W flags for homing]

I appreciate any suggestions and helps from community for the following codes for homing 2 motors.  The current code used H/W limit sensors but I want to disable HW flag and use SW flags instead. I tried to set I197=1, I124=$20000, I7212=0, I7213=0, I113-32000 and I could not make it to work.  Thanks for the help.
