Hi,
A subroutine record calls a user defined function with a pointer to
the record structure

as an arugument. It means you can get a waveform data from input link,
such as prec->inpa.

However, you cannot put waveform data as .VAL field of the subroutine
reocrd.

.VAL field of the subroutine record is defined as DBF_DOUBLE.
It should not be so difficult to combine a subroutine record and a wave
form record

for creating new subroutine record with waveform output.
If you just needs a linear transformation of waveform data, our
colleague has

a record support for such job, by the way.

We also have a concat record which concatenate several waveform (or
scaler) data into

a single waveform data.
regards,
Noboru

hi, all

Has anyone implemented array processing with a

subroutine record?

I want to access the values in a waveform (WFM) record with a

subroutine record, cacultate for each element and pass the array to
the output.

WFM -->|a out|----> WFM

ai -->|b |

ai -->|c | for idx=0..499

| | (a[idx] - b ) * c

| ROUT- |
