Hi,

I think I know the answer to this but wanted to see if there really is a solution:

I want to use a method with a few of the parameters as optional e.g.
loSettings.SetObject("txtLastname",,.T.,.F.)
and then in the method code I have this:
LPARAMETERS tcObjectName, txValue, tlVisible, tlEnabled
where the 2nd parameter is not passed; PCOUNT() does not does help because I have passed the 3rd and 4th params.

Of course in the method code, I get a default value for the second parameter as .F.; but that does not help me to know if it was passed or not because in this case the "value" could be a logical that was passed.

I realize that I could change the order of the parameters so that txValue is last and then PCOUNT() works but the 2 most commonly used parameters are the first 2 and so I would rather have them in the order they are.

What I need is function that tells me if the 2nd paramter ws passed something like IF PARAMETER(2) = .T.

or I need a way for the parameters to default to .null. or something if nothing passed.

Am I missing something that is in the help file?

Thanks,

Albert Gostick
