    Another very basic one, I'm afraid.

    The link says that "length" is a core string function. However, the following will not compile

    Dim D As String * 2, M As String * 2, Y As String * 4
    Dim StartDt As String, EndDt As String, L As Int
    Y = EY.Text
    If D <> "" And M <> "" And Y <> "" Then StartDt = Y & "-" & M & "-" & D
    L = Length(Y)

    It gives the error "Undeclared variable 'length' was used before it was assigned any value".

    It's not a variable - it's meant to be built in...

    Any ideas?

    Length() is a member function of the String object. Do Y.Length instead of Length(Y).

    Create a string 2 characters in length?

    No. A string is a string and can hold as many characters as you want. It is dynamic.

    My pleasure. It also looks like you're trying to manually format a date String. I would recommend against doing that and instead look at the DateTime object and all its member functions. You can set up custom DateTime formats (or use pre-configured ones) and it comes with parsing functions and lots of other helpful stuff. It's much more robust than trying to put together a brittle ad hoc one-time solution.
