That's what I was hoping.

Here's a related question for you, based on your syntax. I have not been using FormSets at all, mainly on published comments by Doug Hennig, as well as a lack of perceived need. What do you use FormSets for, and where do you find them useful? In particular, with the exception of a shared DataEnvironment, what would be the advantages and disadvantages of using a FormSet versus an array of Forms?

FOR EACH loForm IN FormSet
loform.Whatever()
NEXT

versus

FOR lnI = 1 to ALEN(oApp.aForms)
oApp.aForms[lnI].Whatever()
NEXT

(neverminding my iteration routine - that's just there for illustration.)
