Zen,
I use waveform arrays, although my device driver is not ASYN but ht2992 VME
CAMAC SHD.

The sub record may have an OUT link that you can write to from your process
routine (can't recall).  Otherwise you can put your value into the sub
record's VAL (or other 'spare' field) and FLNK to another passive scan record
that can INP and OUT link to the target record's field (assuming that field
can be modified at runtime).

-ps

Subject: CAMAC IO

I am writing a soft IOC based on asyn which will do CAMAC IO via KS3988 GPIB
crate controller.  I have two problems that I am not sure how to solve.
1. write a counted array of bytes containing numeric values to the crate
controller.  What record type is well suited for that?
2. Also, What record type should I use to read an array of bytes from the
crate controller?
Unrelated question is, Is it possible to modify a field value in a record
from within a subroutine?  To be more specific, I have a sub record and from
its process subroutine I want to modify a field in another record.  Can that
be done?
Thanks,
Zen
