How to add a eula text to app

Use some sort of persistent data (Map)
Then in Activity_Create use an if statement like so:
If Map1.Get("EULA") = 0 then
'put dialog code here'
when user confirms: Map1.Put("EULA","1")
End If

Obviously this isn't the correct syntax (I don't have B4A on here right now). But you get the idea...

You can use a Panel with TextView or WebView to show the text.

Thank you guys,i have used a file to check if the user clicked ok JonPM said.
i have found this simple eula src
https://github.com/Agilevent/Eula-Sample/tree/master/src/com/agilevent/eulasample maybe it would be great if someone make a library for B4A from this.
