Hi Smith - I assume you’re referring to something like `fetch 1xyz, async=0`. This means that the PyMOL interpreter should wait until the PDB file is downloaded and loaded before continuing with the next step.
Normally, the commands will be issued one immediately after the other and the next one may start before the current one finishes. So multiple commands may be running at the same time, or asynchronously. For example, if you were to run a script containing the following: fetch 1xyz as cartoon color blue, chain A Depending on the speed of the download, the protein would likely end up looking just like if you only called `fetch 1xyz`, as the other two commands will have started (and finished) before the `fetch` is complete.
