Overview of Expand library functions

        All Functions in the Expand library guide are presented in a
        similar fashion, grouped by functionality into blocks,
        such as 'High Level' MOUSE functions or 1-2-3 related functions.
        The functions have not been ordered alphabetically on
        purpose, as it is probably clearer to find out the relating
        functions this way. The 'Functionality Blocks' are ordered in
        random order.

        Every function is described in a similar fashion, beginning
        by some general comments about the function's purpose and/or
        typical usage. Sometimes there's also some technical information.
        After that, the Clipper syntax is presented followed by a description
        of arguments and/or return values. Finally there will generally be a
        small part of Clipper code that demonstrates the function's typical
        usage. "See Also" references can often be found.

        Sometimes a group of function descriptions is headed by some
        general comments about the functions, do read that information,
        as it may contain valuable/important information.

        Typical usage of most functions is well illustrated in the
        EXPDEMO.PRG program. Refer to those when it is not clear to
        find out how to use the function.
