 Printing Commands
 *****************
 
 `p'
      Prints the value on the top of the stack, without altering the
      stack.  A newline is printed after the value.
 
 `n'
      Prints the value on the top of the stack, popping it off, and does
      not print a newline after.  (This command is a GNU extension.)
 
 `P'
      Pops off the value on top of the stack.  If it it a string, it is
      simply printed without a trailing newline.  Otherwise it is a
      number, and the integer portion of its absolute value is printed
      out as a "base (UCHAR_MAX+1)" byte stream.  Assuming that
      (UCHAR_MAX+1) is 256 (as it is on most machines with 8-bit bytes),
      the sequence `KSK 0k1/ [_1*]sx d0>x [256~aPd0<x]dsxx sxLKk' could
      also accomplish this function, except for the side-effect of
      clobbering the x register.  (Details of the behavior with a number
      are a GNU extension.)
 
 `f'
      Prints the entire contents of the stack without altering anything.
      This is a good command to use if you are lost or want to figure
      out what the effect of some command has been.
