RE: Best Way to find duplicate records in same file

[rob@xxxxxxxxx]

Well, then, primary file it, put a control break indicator on the key 
field(s).  If not L1, delete.
I know, having to code only 1 calc spec turns some peoples stomach's, but 
stuff them.

Probably going to go with following as I need to get the deletes in the
journal for the file

Creat file FILEW with Key on all fields

RPG PGM:

Read File
Chain to FILEW
If not in FILEW
Write FILEw
Else
Delete FILE 
Endif

You can also use OPNQRYF/CPYFRMQRYF to do this (one-time approach):

OPNQRYF FILE(YOURFILE) KEYFLD((KEY 1) (KEY 2)) UNIQUEKEY(*ALL)
CPYFRMQRYF OPNID(YOURFILE) TOFILE(UNIQUEFILE) CRTFILE(*YES)
MBROPT(*REPLACE)

Now UNIQUEFILE has the unique records based on the keys given.
