Need to interupt while loop

[Whacko]

I am using a system key in Mach3 to interupt a while loop by monitoring a led state. The OEM buttons and OEMled's has a low priority in a macro while loop it seems. I have worked around it, but can't locate info on buttons that has a higher priority and is not assigned to Mach3 system. Is there available buttons for such an interupt?
I am monitoring a button/led while in a timer loop as to terminate the loop via external interupt premature to the timeout.

Redo your While conditon Put and "OR" in your while and the other part is your escape conditon

While (what I am waitin on here) OR (IsActive(INPUT2)) (INPUT2 your escape clause, or button, or led here)

Hi Scott, thanks for the input, but that won't work. I'm in a timer loop. Whilst in the timer loop, OEM buttons don't trigger an interupt in the kernell. I think I got the answer though. I didn't think of it but it has something to do with the button group.
