Barbara,
Do you always create object variable references with a preceding 'o' for the variable name. If so you can then do a DISPLAY MEMORY LIKE 'o' to list those object references. However, again if you have declared a reference as a LOCAL within a method or event of a form or a property of a form then it would be hard to find. To bad there isn't a method to allow you to reference through all of the variables that are currently declared and check their type in a loop.
