Just a thought - write an SMP/E USERMOD to REPLACE the IBM-supplied 
ICHRIN03 in SYS1.LPALIB.  Pro:  it eliminates the duplication and LPA load 
sequencing issue.  Cons:  You have to write and maintain MCS, and re-install 
for every OS upgrade (but PRO:  *if* IBM ever changes the format, you find 
out before the first IPL); and if you're a multi-system environment, a 
USERMOD is tough to maintain if the table is not common across all systems.
