Do the values of variables in an ILE CL program get refreshed on
every call to it if it is run within a named activation group? e.g.,
The following program is created with the parameters DFTACTGRP(*NO)
and ACTGRP(EXAMPLE). If it is called repeatedly from another program
in the same activation group, is the value of &LOCAL reset to
'Initial' every time this program is called?
PGM PARM(&ACTION)
DCL VAR(&ACTION) TYPE(*CHAR) LEN(4)
DCL VAR(&LOCAL) TYPE(*CHAR) LEN(10) VALUE('Initial')
<<SNIP>>
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.
