Dynamic: Pulling is always dynamic, as we discussed before. But because we don’t need any global ordering of nodes, it’s very easy to have a dynamic push step as well, as each node only needs to keep a list of its upstream and downstream immediate neighbours. This structure is typically much easier to manipulate than maintaining a globally ordered list (and a lot cheaper than performing a fresh topological sort every time we want to evaluate nodes).
It seems like there were no source files for most of Dyalog APL's history. Instead, images held code and variables. You would pass them around to work with other people. While there are features such as LINK nowadays that make this irrelevant, one can stumble upon forum posts on how to share or run code with images in bewilderment.
