6.3.2 Using lists as buffers
The following example demonstrates the use of a list as a buffer in which the first item added to the stack is the first one to be popped:
pyxplot> myList = []
pyxplot> for (i=1; i
12; i++)
pyxplot> {
pyxplot> if prime(i) { call myList.append(i) ; }
pyxplot> }
pyxplot> while (myList) { print myList.pop(0) ; }

The function prime(x) returns true if x is a prime number, and false otherwise. In the final line, we make use of the fact that a list tests true if it contains any items, or false if it is empty.
