 GetProcAddress()       Retrieves the address of the given module function
--------------------------------------------------------------------------------

   Syntax:              GetProcAddress( <hInst>, <cProcName>, <lPascalType>,
                           <nReturnType>, [<nParam1Type>, ...<nParamNType>] )
                           --> <cProcData>

   Parameters:

   <hInst>              Identifies the module that contains the function.
                        Normally The handle of a DLL, that previously
                        we have loaded with LoadLibrary().

   <cProcName>          The name of the function, or its order number
                        inside the DLL.

   <lPascalType>        True is the function to be used is PASCAL type.
                        Normally most of Windows API functions are PASCAL
                        type.

   <nReturnType>        A numeric value that indicates the type of value
                        returned by the function to be called.

                        The nReturnType possible values are inside FiveWin
                        DLL.ch:

                        #define VOID     0
                        #define BYTE     1
                        #define CHAR     2
                        #define WORD     3
                        #define _INT     4         // conflicts with Clipper Int()
                        #define BOOL     5
                        #define HDC      6
                        #define LONG     7
                        #define STRING   8
                        #define LPSTR    9
                        #define PTR     10
                        #define _DOUBLE 11         // conflicts with BORDER DOUBLE

   <nParam1Type>        Are the different types of parameters that will be
   <nParamNType>        supplied as parameters when calling to the DLL
                        function. They are numeric values as the above
                        <nReturnType> values.

   Returns:

   <cProcData>          A string which contains a binary representation of
                        the DLL function to be called plus necessary information
                        about the type, parameters and return type.

                        The information here contained is vital to properly
                        build a C-language alike stack and its manipulation.

   Observations:        This function is automatically used from the FiveWin
                        DLL management xBase commands. We strongly recommend
                        to use the xBase commands to use this function, as
                        An easier way and avoid possible mistakes.
