Mistakes to avoid with DCL

  • Never repeat a symbol more than three times in a row. When a fourth would be needed, the subtractive form takes over.
  • Only I, X and C may be placed before a larger symbol to subtract, so DCL never contains forms such as VX or LC.
  • Read DCL as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
