Globals in Subs

[Jim Brown]

Does b4a have a mechanism for having variables which remember their values yet are unique to the sub (that is, not 'global' to the whole program)?

Here for example, I want the variable n to be private in the test() sub yet retain its value. Currently, the value is always re-initialised each call:

Sub Globals
End Sub

Sub Activity_Create(FirstTime As Boolean)
   For i=1 To 5
      test
   Next   
End Sub

Sub test()
   Dim n As Int
   n=n+1
   Log(n)
End Sub

No, it doesn't.

A not very elegant workaround is to declare a global variable named: sub_test_n and then only use it in the current Sub.
