Joel, that's the way it's documented to work (see the entry for the
STATIC keyword in the reference).
  " ... it is _not_ reinitialized again, even if reinitialization occurs
   for global definitions as part of normal cycle processing."

Your best bet is either to move the static variable into global
definitions, or set up some other static variable in globals that
says to initialize subproc static.

D inzSubpStatic    s         n      inz(*on)

P subp             b
D staticVar        s       10a      static inz('x')
C          if     inzSubpStatic
C          eval   inzSubpStatic = *off
C          reset  staticVar
C          endif
P                  e

By the way, don't forget that each module has its own LR.  It's not the
program that ends with LR on, it's the main procedure in the module.
