UPPER()


Syntax:     UPPER(<expC>)

Purpose:    To convert lower case alphabetic characters to upper case.

Argument:   <expC> is the character string to convert.

Usage:      UPPER() has a number of different uses.  A common use is to
            compare strings where the specific instance of casing is not
            known.  For example:

            message = "Greetings"
            ? UPPER("greetings") = UPPER(message)

            UPPER() is also useful for creating case independent index
            key expressions.  For example:

            USE Customers
            INDEX ON UPPER(Last) TO Customers
            *
            * Later, use the same expression to lookup Customers.
            mlast = SPACE(15)
            @ 10, 10 GET mlast
            SEEK UPPER(mlast)
