*** Calling WSC from Power Builder ***

We do not use the Power Builder compilers, although we have several
customers that do. To use WSC in Power Builder:

1.  Install the WSC library in the Power Builder path. Note that for
    Power Builder Version 5, this means WSC16.DLL.
   
2.  Declare the functions in the Power builder's Declare global 
    external function menu:

        Function integer SioDone(integer Port) library  "Wsc16.dll";
        Function char SioGetc(integer Port) library "Wsc16.dll";
       ...
       
    These functions are defined in the file WSC.PBI.
    
3.  In order to call the functions inside Power Builder, follow this example:

        Integer Result, COM1
        COM1  = 0               

        Result = SioGetc(COM1) 
        If  Result < 0 then 
            SioDone(COM1)
            ...
            return
        end if
        ...
