I don't understand it either!  Parameters on the /400 don't seem to work well
at all unless you adjust them for each case.  RPG-CL numeric variables need a
length (even calling QCMDEXC) of 15.5 -- what's up with that?  It is SO
annoying to submit an RPG program (don't know if the other languages are like
this) from a CL using data structures, and have the second structure "cave
in" on top of the first if the first isn't completely populated!!!  The BPCS
"submit job" API populates the last character of the first variable with an
"X" if it is blank to prevent the latter, but why does it happen in the first
place??!!!
