Hello,
 
I implemented a simple sub record to read a series of individual values from different ai records and write them into the elements of a waveform record, the code for which is attached.  It should be straightforward to use the same method to read elements from one waveform, perform your calculation and write the calculated values to another.  Please note that the attached code uses INPA as the address of the output waveform record.
 
Hope this helps.

Subject: Waveform calaulation for each element

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
                | SUB-  |    
                | ROUT- |
                | INE   |
