General Purpose First In - LastOut (FILO) Integer Stack. Used in all code modules. Can be used manage a pool of entities and much more. Note a majority of the code generated with the TypeWriter Code Wizard:)

Summary of functions:

stackCreate(size%) Creates a stack object of a specified size.

stackIndexCreate(size%) Creates a stack of indexed integers. Primarily used to create a list of object ids. Object IDs are pushed and poped as needed.

stackDelete(this.stack) Removes a stack from memory.

stackPush(this.stack,value%) Inserts a value on the stack.

stackPop(this.stack) Extracts the last value inserted on the stack.
