Description #

This routine pushes the current value of Ans into a special Ans stack. The PopAnsStack command is the reverse function, popping a value back into Ans. It is recommended that you call ClearAnsStack before touching the AnsStack in case another programmer failed to clean it up properly.

If no second argument is provided, then the value in Ans is pushed to the default stack, called Ans0. However, a second argument between 0 and 9 inclusive will instead specify that the value should be pushed to one of Ans0 through Ans9. PopAnsStack allows a similar second argument.
