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?

Waveform and genSub are the ones I'd look at first.

2. Also, What record type should I use to read an array of bytes from the
crate controller?

Waveform.

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?

Yes, but it's not a good idea to do it. Better to use the genSub record, because it has output links.


Thanks, Zen
