 INWORD()
 Reads in a 16-bit word from a port
------------------------------------------------------------------------------
 Syntax

     INWORD(<nPort|cHexPort>) --> nWord

 Argument

     <nPort|cHexPort>  Designates a port address from which a word with a
     16-bit value is read.  This value can be a decimal integer or
     hexadecimal string.

 Returns

     INWORD() returns the word read from the designated port, or a value of -
     1 when an error occurs.

 Description

     Clipper Tools always attempts to offer finished solutions at the
     highest-possible level for such standard hardware as a serial interface
     port.  However, if you read highly specialized systems and their ports
     from Clipper, use INBYTE() or INWORD().  INWORD() allows you to read
     from interfaces that return the data from a port as a 16-bit value.

 Note

     .  A returns random value for a nonexistent port or one that
        cannot be read.

 Examples

     Show a read from a 16-bit port:

     .  With a decimal parameter:

        ? INWORD(512)           // Read from an additional device

     .  With a hexadecimal parameter:

        ? INWORD("200")         // The same port address
