main function takes a piece of text which is input by user on text input and abbreviates it to an acronym.

Hi,

Global function example see on scrTitle and scrGlobalFunctions in [ACtech demo project](https://x.thunkable.com/projects/5d70f93f8a62b4079eedaff2/project/properties/designer/)

Global functions cannot work with interface components located on other screens.

Best regards, Alex

Would it be possible using Functions with Variables or vice versa?
