It is not possible. You could create a custom Type containing ...

(Erel was faster ?)

... containting the target (code_rdm) and the routine name.
Click to expand...
Example:
B4X: 
Type tToCall(Target As Object, SubName As String)



Dim ToCall As tToCall
ToCall.Initialize
ToCall.Target = "modXYZ"
ToCall.SubName = "Routine"
AnObject.Tag = ToCall



ToCall = AnObject.Tag
CallSub(ToCall.Target, ToCall.SubName)

I wrote AnObject as example... any object that has a property like Tag, which is of type object.

B4X: 
Type tToCall(Target As Object, SubName As String)


Dim ToCall As tToCall
ToCall.Initialize
ToCall.Target = "code_rdm"
ToCall.SubName = "NbrTotalPIDToSynchro"
pb.Tag = ToCall


ToCall = pb.Tag
CallSub(ToCall.Target, ToCall.SubName)

I do that to test in the Sub Activity_Create(FirstTime As Boolean)

B4X: 
    Dim obj As Object
    Dim pb As Panel
    pb.Initialize("")
    Dim ToCall As tToCall
    ToCall.Initialize
    ToCall.Target = "main"
    ToCall.SubName = "test"
    pb.Tag = ToCall
    ToCall = pb.Tag
    result = CallSub(ToCall.Target, ToCall.SubName)


B4X: 
Sub test As Int
    
    Return 5
End Sub

and I have an enrror on the last line

the error is
java.lang.NumberFormatException: For input string: "null"
