Fōrmulæ programs are not textual, visualization/edition of programs is done showing/manipulating structures but not text. Moreover, there can be multiple visual representations of the same program. Even though it is possible to have textual representation —i.e. XML, JSON— they are intended for storage and transfer purposes more than visualization and edition. To use it, open the web address [https://formulae.org/ formulae.org] in your browser. it is preferable to use this environment in a desktop web browser. Programs in Fōrmulæ are created/edited online in its [https://formulae.org website], However they run on execution servers. By default remote servers are used, but they are limited in memory and processing power, since they are intended for demonstration and casual use. A local server can be downloaded and installed, it has no limitations (it runs in your own computer). Because of that, example programs can be fully visualized and edited, but some of them will not run if they require a moderate or heavy computation/memory resources, and no local server is being used. It is not necessary to install anything else. ~~In '''[https://formulae.org/?example=Interactive_programming this]''' page you can see the program(s) related to this task and their results.~~ A page with information is shown. You can start a new script using the [[File:Fōrmulæ - Interactive programming 05.png\|border]] tool (new document).
