Take a look at the wait record (misnomer - should be called the "whiz bang zoom
record"). 

>From the Record Reference manual:

-------

Output Link Execution Options

The outputs of the wait record are not necessarily executed every time the 
record processes. This allows "downstream"
processing of records to be done conditionally. The "output execution" options 
are decsribed below.

      Every Time: Outputs are executed every time the record processes.
      On Change: Outputs are executed if the result of the calculation (VAL) is
       different than the previous time the
      record was processed.
      When Zero: Outputs are executed if the result of the calculation is zero.
      When Non-zero: Outputs are executed if the result of the calculation is
       not zero.
      Transition To Zero: Outputs are executed if the result of the calculation
       is zero and the previous value was not zero.
      Transition To Non-zero: Outputs are executed if the result of the
       calculation is not zero and the previous value was zero.

Hope this helps.
