   Sorry Wolfgang I'm not sure if I've fixed my newsreader yet!   
      
      
   You spotted an error in my decoder of mov al,0x86; of course it should be:   
      
             mov al,0x45         ; fallthru   
             sbb al,0            ; '+'->62   
             ...   
      
   I'm having difficulty with your decoder;   
      
   I see this:   
      
                     sub al,0x47   
                     jnc havenum     ;0410 (p),06(s)   
                     add al,6        ;no gain with sub al,fa   
                     cmp al,0x1a     ;(s)   
                     jc  havenum     ;040a (p)   
                     add al,0x45   
                     cmp al,0x33     ; '/'   
                     ja  havenum     ;b004 (p)   
                     mov al,0x3f   
                     sbb al,0        ;(p)   
   havenum:   
      
   Am I missing some code? as G-Z don't get the right values.   
      
   I like your simple ror and shr, luckily we're no longer decoding in place, or   
   you'd zap the source.
