IF

[luiscambuston]

I am running this simple code

cUserName := "Luis"

If cUserName <> ""
? "Not Empty"
Else
? "Empty"
EndIf

The response is "Empty".
I tried everything that I can think.
Driving me crazy...

Thanks

Try

if len(alltrim(cUserName )) > 0

Basically this ! variable == "" works
This variable <> "" does not
this variable != "" does not....
