to manipulate it.
Typically a sequence will push one of the
parameters onto the stack and then print it in some format.
-Often more complex operations are necessary.
+Print (e.g., "%d") is a special case.
+Other operations, including "%t" pop their operand from the stack.
+It is noted that more complex operations are often necessary,
+e.g., in the \fBsgr\fP string.

Binary operations are in postfix form with the operands in the usual order.
That is, to get x-5 one would use "%gx%{5}%-".
