Looks like Penko thought "constant support" meant live technical support to be provided by Erel. I also thought that at first. Everest should have explained the topic, in the first post itself.
B4A has no 'constant support'.
The only constants B4A are cPI, cE, CRLF.
I use variables as 'constants' in my programs.
Dim them in Process_Globals with 'c' as prefix and set the value.
They are not real constants because their value can be changed anywhere in the program.

In my classes I find it easier to just make a public function that returns a value as a constant. Then you can comment and get the documentation to show too.
