Subject: C function in when() clause of sequencer

Hi,
Is it possible to call a C function to avoid having a very cumbersome when clause in my epics
sequencer program? I get some compiler error or other when I try different variations,
so I'm hoping someone can tell me the best way to handle this.


What I want is instead of this:
when ((vacuumReading >vacuum_high) ||(tempReading >tempCerm_high)
         ||(eminusReading >electron_high) ||(pmtReading >pmtlight_high))
    {
     } state backOff

I would like to do this:
%{
/*
   This function checks for exceeding any of the soft limits.
*/
static int softCheck()
{
   return(
   (vacuumReading >vacuum_high)
   ||(tempReading >tempCerm_high)
   ||(eminusReading >electron_high)
   ||(pmtReading >pmtlight_high)
   );
}
}%

...
     when (softCheck())
     } state backOff

Thanks,
Dennis
