   Make your token syntax LL, as supported by CoCo/R.   
      
   The selection amongst decimal and hexadecimal numbers should occur   
   *before* the digits are scanned, e.g. by "$"{hexDigit}, not afterwards.   
   When the lexer has to switch from decimal to hex mode when a hex digit   
   is encountered, a trailing "H" is quite superfluous.
