  If a variable will establish a new initial value on each invocation, 
versus only on the initial activation, depends on "whether the variable 
is an automatic variable or a static variable. The difference between 
the two is in the storage for the variables. For automatic variables, 
the storage is associated with the call of the program. Every time a 
program is called, a new copy of the variable is placed in automatic 
storage. A change to an automatic variable remains in effect only for 
the program call."

  There is no declarative feature for *STATIC storage in a CLLE or CLP. 
 There is only *AUTO storage that is available for the STG() parameter 
of the DCL command.  The given DCL for variable &LOCAL will default to 
STG(*AUTO), and will be initialized to 'Initial' on each invocation:

  This nature of storage for declared CL variables holds, irrespective 
of the choice of either ILE [with activation group] or OPM.
