Stack Control
*************

`c'
     Clears the stack, rendering it empty.

`d'
     Duplicates the value on the top of the stack, pushing another copy
     of it.  Thus, `4d*p' computes 4 squared and prints it.

`r'
     Reverses the order of (swaps) the top two values on the stack.
     (This command is a GNU extension.)
