RE: Converting names & street names

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

Huh?

I fail to see how EBCDIC is any more consistent than ASCII.

In ASCII, lowercase comes after uppercase.

In EBCIDIC, assuming CCSID 37 then by default lowercase comes before
uppercase.

CREATE TABLE QTEMP/TESTCW (FLD1 CHAR (10 ) NOT NULL WITH DEFAULT)
INSERT INTO QTEMP/TESTCW VALUES('Charles')
INSERT INTO QTEMP/TESTCW VALUES('CHARLES')
INSERT INTO QTEMP/TESTCW VALUES('APPLE') 
INSERT INTO QTEMP/TESTCW VALUES('apple')
INSERT INTO QTEMP/TESTCW VALUES('charles')

select * from testcw order by fld1 
apple   
charles 
APPLE   
Charles 
CHARLES 

Now if you change the sort sequence to *LANGIDSHR then you get:
APPLE   
apple   
Charles 
CHARLES 
charles 


HTH,
