Tim,

the record sets up watchdog timers to do the delayed processing. There
is currently no easy way to cancel the operation of a seq record once
you pushed the button.

(You could of course look at the seq record code and write a function to
be used within a subroutine record that cancels the timer and resets the
seq record to a usable state. That would not be a good design neither
easy to do, though.)

(Or you could add this functionality to the seq record. I'm sure there
are other people who would appreciate this.)

I would switch to using the sequencer with a state machine that looks
for a "cancel" bo record. When the sequences are rather long or
complicated and don't need many instances, the sequencer is the better
tool.

Good luck!
