Hi Jianguo,

Please take a look at the "genSub" record. The code and
documentation are available from:

www.observatorysciences.co.uk/epics.htm

This is a general purpose subroutine record which can handle
arrays, scalars and even user defined structures. It allows
for up to 21 inputs and outputs. Each input
and output can be user specified as an array or a scalar. So
you could read in an array from a waveform record and scalar
values from your "ai" records, perform the calculation in
the subroutine, write the result in VALA, which would be
configured as an array. This could then be linked to another
waveform record.

If you decide to use it, please let me know if you have any problems.

Cheers,

Andy
