How to use PUSH/POP

  • Please help me to understand.

    I am curious about the use of the Push(var) Pop(var) function and have no relevant use case where I can understand it fully. Could I get an example(s) of how it might be used. Mostly I don't understand how to reference "the stack" in the way I might reference a variable.

    My first impression was to use it to "stack" photos, maybe as a variables referencing image #'s, then use some button action to push or pop them from the stack for viewing.

    I don't actually need a new photo gallery, I have many options to choose from, I just want to understand this set of functions/commands to learn a bit more. So only a basic example is ok.

    any help is much appreciated
