Clarion - Proposed Picture Notation for Hex,Octal and Binary

PictureNotation.txt

It would be great to extend the picture notations to Support Hex, Binary and Octal Notations.

Ideally these new pictures would be available for use in the RTL and Topscan 

The following specification is intended to match the current Language Reference for @N pictures
-----------------------------------------------------------------------------------------------
@[B|b|O|o|H|h] [currency] [sign] [fill] size [grouping] [places] [sign] [currency] [B]

  Base 
       @[N|n] = Decimal - status quo, will not alter (see existing doc for @N)
       @[B|b] = Binary 
       @[O|o] = Octal (somewhat confusing with Zero)
       @H     = Hex   (UpperCase digits, ABCDEF)
       @h     = Hex   (LowerCase digits, abcdef)

  Currency - same as @N notations
       Can be used as an Indicator of the base
          None           - @H8
          Leading        - @H~0x~8
          Trailing Upper - @H8~H~   
          Trailing Lower - @H8~h~   

  Sign - Only applies to @N
  
  Fill - same as @N notations
  
  Size - same as @N notations 
  
  Grouping 
       for decimal there are:
           None            produce commas
            . (period)     produce periods
            _ (underscore) produce spaces
            : (colon)      produce colons
            - (minus)      produce dashes (requested, but worried about confusion with negative values)


        All of the decimal pictures group on 3 Digits
           (see notes in [places] below using places for grouping)

        Add an explicit comma
            , (comma)      produce commas  (needed for places as grouping control)

       
 Places
       Since the Binary/Octal/Hex values would be considered integers
          we can co-opt this value to control how many digits to group on.
          (the Default Digits might vary by base (to be determined))

       So, for a value that would show in hex as: [89ABCDEF]          
         @H9_4   => 89AB CDEF
         @H11_2  => 89 AB CD EF
         @H8_0   => 89ABCDEF     override default grouping

         @H11    => 89,AB,CD,EF  !default number of digits (whatever is decided, shown here as 2)
         @H11_   => 89 AB CD EF  !default number of digits (whatever is decided, shown here as 2)
         @H11.   => 89.AB.CD.EF  !a bit strange - should be reviewed
         @H11:   => 89:AB:CD:EF  

         @H9,4  => 89AB,CDEF    !explicit comma grouping symbol
 
         NOTE: At first I wrote all of those (above) @H8 something, 
               but it was pointed out that the grouping chars add to the number of digits

 Trailing B - Blank When Zero  - same as @N notations
