Hi Everybody!

Is it possible to extend channel access to take two optional parameters
(for array fields only), so that we can read/write only a few consecutive
elements of the array (N elements starting at index I, default to the whole
array)?

Another idea, is it possible to extend the registering of monitoring
callbacks to take some optional parameters?  And the IOC would check
against those extra conditions to decide whom to send the callback.

These features would make EPICS irresistable to some hardcore other-
package users.

How much work will this be?  Will it break all the existing clients?

Thanks and best regards,
Dehong
