selnew - Create a New Work File
If the list of objects belonging to a change request needs to be stored in a global rather than a local array, a unique key to the ^%vcsel work file is required. This key can be any non-numeric value. It is the responsibility of the calling program to ensure that the key is not already in use by another process. This function can be used to allocate a guaranteed unique key which can be used once and discarded.
It is the responsibility of the calling program to delete the work file contents after use.
