Does a method exist?

How can I tell whether a method exists in an object?

I have a process that is passed a form as a variable and I want to run a
particular method if it exists on the form.

Running TYPE("MyForm.MyMethod") return "U" even if the method exists.

I could probably just instantiate the method and handle the erorr if it
doesnt exist but there must be a more elegant way?

Any ideas?

Cheers
David

You can use PemStatus()
oForm = CREATEOBJECT('Form')
? PEMSTATUS(oForm, 'Show', 5)
? PEMSTATUS(oForm, 'Unknown', 5)
