I have a flag field, empty at the start, that I want to flag with a "Y".

Finding that set of records with empty fields,

Enter find mode []

Set Field [invoice::processed; ""]

Perform Find []

doesn't work.

Enter find mode []

Set Field [invoice::processed; isempty(invoice::processed)]

Perform Find []

doesn't either.

If, instead, I enter "N" in the field first, then later:

Enter find mode []

Set Field [invoice::processed; "N"

Perform Find []

That works fine.

What is the syntax for a found set based on an empty field? Or what is a better approach?

Thanks

An equal sign "=" finds empty fields.

Or, an asterisk "*" or other criteria ("Y" in your case) and then Omit.

Sunofagun, you're right.

I'd have never found (or guessed) that in a bunch of years.

thanks much.
