RE: sorting

The default sort order for character data is by hex value.  In EBCDIC, the
digits 0-9 are hex values x'F0'-x'F9', which puts them at the end of the
sort, after the alphabetic letters.  However, in ASCII, the digits are
x'30'-x'39', while the letters start at x'41'.  Therefore, in ASCII, the
digits come BEFORE the letters in ASCII.

This has been an issue in ASCII/EBCDIC since the olden days.  Welcome to the
wonderful world of distributed processing... <wry grin>
