We have been taught that we should use byreference() function to pass pvs from process to process. This saves memory. As it relates to a CDT, we are being instructed not to pass a CDT to a sub process as a byreference() function. 1. Why is this? 2. If we do not use byreference() then additional memory will be used in the sub process - this defeats the memory savings.
After reading on the forum it seems that many will create a CDT with many fields in them and then processes using the CDT will only use some of the fields. If you create a CDT specific for a process, wouldn't it make send to pass the CDT to the sub processes as a byreference()?

Passing CDTs byreference() will cause errors to occur when the version of the CDT is different between the two processes. Thus if you pass CDTs by reference in long running processes, and you update the CDT, the inflight processes will throw an error when it triggers a new sub process that attempts to use the newest version of the CDT.
