Just as the (UDS) LDA isn't written to job storage until LR, the external
switches aren't written to the job until LR.  You can SETON and use U1 in
the first program, but it hasn't been propagated to the job yet.  This
behaviour is well documented in the RPG Reference:
http://publib.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/QB3AGZ03/1.4.2.1  That's
why the CL program works: it immediately sets the job values via CHGJOB
SWS().

If you really must use external indicators, stick with your CL setting
program.  I would strongly recommend passing parameters instead.  I've found
that parameters are much more flexible and easy to use and debug.
