popFromStack


Syntax:

popFromStack (thisStack);

Purpose:

Removes the first element from a stack. If there were previously n elements in the stack (numbered 0 to n-1) there will now be n-1 elements in the stack (numbered 0 to n-2) with thisStack[0] now containing the old value of thisStack[1], thisStack[1] now containing the old value of thisStack[2] and so on. Calling this function is equivalent to calling the dequeue command.

Return value:

The command returns the value which was removed; the old value of thisStack[0].
