@Dick B Sorry that I have so much trouble in locating the proper entries in the docs.
No problem, you'll find your way around the docs soon enough. Sometimes it's just as quick to throw a quick search at Google: "Xojo iOS Random Number" for example, and you often get back a link to a page from the docs and a few links to forum answers.
@Dick B Anyway this helped. I have one further problem to tackle namely writing information into a sql database. I used MBS plugins on the desktop app. For iOS I searched in iOS examples but could not find a good example but maybe you have a pointer. Otherwise I will start a new conversation.
Check out the Example Projects folder bundled with Xojo. I see three SQLite example projects in Example Projects > iOS > Database.
