    Re: Please, need help in understanding the following functions

    These are no functions at all, but are declarations of several variables.
    Also I have to state that nearly all of these lines are WRONG.
    Every variable has to declared explicitly like
    Wrong: Public textval , dtext, SString, Sendstr, Rtext As String
    only the Rtext is declared as string. The others become Variant, because they carry no AS statement.

    Right: Public textval As String , dtext As String, SString As String, Sendstr As String, Rtext As String

    Also right: Public textval$ , dtext$, SString$, Sendstr$, Rtext As String
    This uses the shorthand $ for AS String.

    Similar you can use % for AS Integer, ! for As Single, # for As Double and & for As Long.
