pcxX2()

         Returns the final coordinate X of the PCX

    Syntax:

         pcxX2 ( cFile ) -> cCoorX2

         cFile : Name of the PCX file

    Description:

         It returns the final coordinate X of the PCX file. This value
         usually determines on its own the PCX width, even when the exact
         value would be like:

                nAnchura := pcxX2 - pcxX1 + 1

         But due to the pcxX1 usually takes value 0, the value pcxX2 + 1
         indicates the width by itself.

    Return:

         The value of the final coordinate X.

    Example:

         ? pcxX2 ( "c:\fast\lib\fast.pcx" )
