Hi all

    I have a problem with Cobol and secuential files when migrating from
MVS to AIX.

    I have many batch processes that do 3 steps:

        1 - extract data from database and write secuential file
        2 - sort the secuential file (external tool like syncsort)
        3 - generate report

    Secuential files in Cobol set for Aix have two real files one like
filename.txt and other hidden file named .filename.ddmea .

    If the sort not have 'INCLUDE' or 'OMIT' options i can copy the
original .ddmea file with the name of sorted file and all work fine
but.... I have some sort processes with 'INCLUDE' option set...

    Someone know any utilitie for generate .ddmea file from secuential
file?
    Someone know the .ddmea file specification?

NOTES: I can't use 'line secuential' files... i have packed data.
              The migrated application is very very old and big!!!

T.I.A.

Salud y Suerte!!!!!!!!!!
