Yes.  That's true...  That Scott guy sure is smart! :)

Here's a quote from the WSDS ILE RPG Reference manual:

   For a local variable of a subprocedure, the STATIC keyword specifies
   that the data item is to be stored in static storage, and thereby hold its
   value across calls to the procedure in which it is defined. The
   keyword can only be used within a subprocedure. All global fields are
   static.

   The data item is initialized when the program or service program it is
   contained in is first activated. It is not reinitialized again, even if
   reinitialization occurs for global definitions as part of normal cycle
   processing.

   If STATIC is not specified, then any locally defined data item is
   stored in automatic storage. Data stored in automatic storage is
   initialized at the beginning of every call. When a procedure is
   called recursively, each invocation gets its own copy of the storage.
