These functions allow you to perform basic programming tasks without being a programmer. These are used to organize or control your other actions. For example you can set actions to loop, to occur in order or simultaneously or you can make actions dependent on certain conditions being met.
On the other hand, if you DO want to undertake some more complex programming then in Opus Pro you can also add a script object and type in even more complicated lists of commands.
