Hi Stefen,

I think you don't want to do this.  It's hard enough to write a record that defends itself from all the possible ways and times that its fields can be written to from outside, without having to contend with code that works around the protections EPICS provides.  It's unfortunate that the sub record has no output link; that would probably be a better solution for you.  I don't know all your requirements, but I'd try the aSub record, which has output links, and see if it can accomplish what you want.
