$ModuleNumber
gives the current serial number to be used for local variables that are created.
Details
- $ModuleNumber is incremented every time Module or Unique is called.
- Every Wolfram System session starts with $ModuleNumber set to 1.
- You can reset $ModuleNumber to a positive machine integer, but if you do so, naming conflicts may lead to inefficiencies. »

$ModuleNumber is also used by Unique to create new symbols from given ones:
If given a string, it creates the first available symbol of the form xnnn:
You can reset $ModuleNumber:
However, its next use may cause $ModuleNumber to be incremented more than once due to conflicts:
