My first take would be a simple subroutine record which does the
compares you want and returns success or failure.

Make that a genSub record if possible so it can read both waveforms
automatically through its input links (the genSub can transfer scalars
or arrays through its link fields). Then all you need to do is compare
the array elements inside the C subroutine and set VAL to a true/false
result.

Subject: checking the content of the waveform record
Does anyone know what is the easiest way to check the content of the
waveform record against predefined one? There is a record with 36
elements and we have to raise an alarm if any of it's elements is
differ from reference one. Of cource I can use many subArray records,
one for every waveform element, then several calc records and so on
.. But may be there is more elegant way of doing that?
Thanks,
Vladimir
