Interrupt routine for remote switch in UIFlow

[Werner_G]

Putty, the walking robot can go forward or backwards. When walking, I cannot stop or switch direction using a remote switch, because I cannot interrupt the flow. An interrupt routine is needed I guess. I found examples for a H/W pin interrupt, but not for S/W. Can anyone please help me?

Maybe you have better idea!
