 Registers
 *********
 
    DC provides at least 256 memory registers, each named by a single
 character.  You can store a number in a register and retrieve it later.
 
 `sR'
      Pop the value off the top of the stack and store it into register
      R.
 
 `lR'
      Copy the value in register R, and push it onto the stack.  This
      does not alter the contents of R.
 
      Each register also contains its own stack.  The current register
      value is the top of the register's stack.
 
 `SR'
      Pop the value off the top of the (main) stack and push it onto the
      stack of register R.  The previous value of the register becomes
      inaccessible.
 
 `LR'
      Pop the value off the top of register R's stack and push it onto
      the main stack.  The previous value in register R's stack, if any,
      is now accessible via the `lR' command.
