Examining object variables

[catalina36]

Is there any way to determine if an object variable points to an instantiated object? Presently I’m trapping the Error 91, however I would like to employ a more proactive approach.

Thanks for helping a beginner.

Hiya,

yes, there is. If an object variable doesn't point to an instantiated object, it points to NOTHING, so you can do this:

If ObjectVariable is nothing then

alternatively, you can do the following:

rc = typename(ObjectVariable)

and, if the object variable doesn't point to anything, rc will become equal to EMPTY

The first way's the best way, though (in my opinion).

Paul,

Thanks for the great solutions. I like the first approach the best as well!
