FT_BYT2HEX()
 Convert byte to hexadecimal version of its binary value
------------------------------------------------------------------------------

 Syntax

      FT_BYT2HEX( cByte ) -> cHexValue

 Arguments

     <cByte> is the byte to convert.

 Returns

     Three-character string, consisting of two digits of hexadecimal
     notation and letter 'h' to signify hex.  Returns NIL if parameters are
     faulty.

 Description

     Can be used to show results of bit manipulation, both before and after.

     This function is presented to illustrate that bit-wise operations
     are possible with Clipper code.  For greater speed, write .C or
     .ASM versions and use the Clipper Extend system.

 Examples

     These three code lines perform a bitwise AND on bytes with values of
     CHR(20) and CHR(36), and deliver the result as a string in hexadecimal
     format, using 'h' to signify hexadecimal.

          ? FT_BYT2HEX(CHR(20))         // byte1: '14h'
          ? FT_BYT2HEX(CHR(36))         // byte2: '24h'

          ? FT_BYT2HEX(FT_BYTEAND(CHR(20), CHR(36)))
                             // result: '04h'

     For a demonstration of Clipper bit manipulations, compile and
     link the program BITTEST.PRG in the Nanforum Toolkit source code.
