At this time, you can assign more than one object ID to a WPS object. To do this, create an object with a new object ID. After that assign one or more new object IDs to the object using SysSetObjectData. Now you can use the original object ID or one of the new object IDs to refer to the object.
The explanation for this from Greg Czaja (see EMail Addresses) is:
"What really happening is that WPS will assign a new ID (and it will be stored in the object's properties but the old one will NOT be removed from OS2.INI -> PM_Workplace:Location. This allows you to refer to an object using both - the old and the ID's. At least from a REXX or PM program - WPS will use only the new one."
