ok then lets declare a string in main named mystring and assign to it the word testword1.
Modify the string in B4XPage1 to testword2 and read it and log it in B4XPage2.
That is what i want to do.

I don't see why you can't do that.

Here you have an example.
I made the variables available in 2 ways:
- Declared in Main Activity
- Declared in a separate Code Module
When the app start both the variables in Main and in Vars module are set to something and logged.
Then you can set both variables to something else clicking the button, that will log them again.
Go to Page 2 and you can log the variables again.
Hope it helps.

I made another example declaring the variables in the B4XMainPage module, that way the principle is cross-platform.
The Starter module does exist only in B4A, and the Main modules are platform specific.
You can modify the variables in any module in Edittext views.

Only tested with B4A.

I have not looked at Sagenut's example.

The separate code module is better. Yes it works. Thank you

I usually end up with at least 2 Code modules that contain global variables. Usually an AppData module which stores App Name and anything else relevant (could go in the Main Module but i like to keep them separate) and a DataConst module which stores Constants used to access Map Data etc.
