Android Question understanding b4a obfuscation

[Addo]

i have followed this tutorial

https://www.b4x.com/android/forum/threads/code-obfuscation.13773/

to understand how to obfuscate/harden sensitive data after decompling

the variable is process globals are obfuscated but now i am trying to obfuscate A sub by doing the following

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Dim iamatext As String = "catch me"
    Dim subName2 As String = "Test_2"

End Sub


 Test_2
    Log("b")
End Sub

but i can see the sub as a plaintext after decompiling what is my mistake ?

There is no relation between the strings and the sub names. Subs without an underscore and that are not called with CallSub will be obfuscated.

Now all clear I didn't realise if I use callsub will ignore the obfuscation thank you @Erel
