Re: Your favorite hex conversion routine - ILE

Hi Booth,

HTML source I've seen has something like this:

    bgcolor=#ffffff

Using Barbara's prototypes, here's a procedure to return the #ffffff portion
of the above example.  It's used like this:

    c            eval    Color = HTMLcolor(255:255:255)

The procedure is:

     p HTMLcolor       b

     d HTMLcolor       pi             7a
     d  Red                           5i 0 value
     d  Blue                          5i 0 value
     d  Green                         5i 0 value

     d Result          s              7a

      * Convert each color to hex and append to result
     c                   eval      Result = '#'
     c                   callp     cvthex1To2
(%addr(Result)+1:%addr(Red)+1:2)
     c                   callp     cvthex1To2
(%addr(Result)+3:%addr(Blue)+1:2)
     c                   callp     cvthex1To2
(%addr(Result)+5:%addr(Green)+1:2)
     c                   return    Result

     p                 e
