# Call code with commands and EXEC > Register commands with component.command() and call them with CMD(), or call a plugin method with EXEC('plugin/method').

Use it for actions such as "open this window" or "refresh that list". The global `CMD(name)` is declared to reach every component, but in jComponent 20.014 it cuts a name that has no space, so it does nothing: use the instance, or `EXEC()`. - `EXEC('plugin/method', a, b)` calls the method `method` of the plugin that lives on the path `plugin`; a plain function name (`EXEC('myfunction')`) calls a global function. The `exec` command of `ui-bind` and the `exec` option of many components take the same names. ```html public/index.html jComponent
