{CQ6363 Notes: This procedure was altered for CQ6363, but then changed back to its original form, as it is now.

The problem is that in LOM1T, there are numerous entries in the HOSPITAL LOCATION file (44) that are lower-case,
resulting in a "B" xref that looks like this:

^SC("B","module 1x",2897) = 
^SC("B","pt",3420) = 
^SC("B","read",3146) = 
^SC("B","zz GIM/WONG NEW",2902) = 
^SC("B","zz bhost/arm",3076) = 
^SC("B","zz bhost/day",2698) = 
^SC("B","zz bhost/eve/ornelas",2885) = 
^SC("B","zz bhost/resident",2710) = 
^SC("B","zz bhost/sws",2946) = 
^SC("B","zz c&P ortho/patel",3292) = 
^SC("B","zz mhc md/kelley",320) = 
^SC("B","zz/mhc/p",1076) = 
^SC("B","zzMHC MD/THRASHER",1018) = 
^SC("B","zztest clinic",3090) = 
^SC("B","zzz-hbpc-phone-jung",1830) = 
^SC("B","zzz-hbpcphone cocohran",1825) = 
^SC("B","zzz-home service",1428) = 
^SC("B","zzz-phone-deloye",1834) = 
^SC("B","zzz/gmonti impotence",2193) =

ASCII sort mode puts those entries at the end of the "B" xref, but when retrieved by CPRS and upper-cased, it
messes up the logic of the combo box.  This problem has been around since there was a CPRS GUI, and the best
possible fix is to require those entries to either be in all uppercase or be removed.  If that's cleaned up,
the logic below will work correctly.
