Hi friends,
I need some clarification regarding sorting.
//S010 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SORTIN DD DSN=MSI1390.TEST.INFILE,DISP=SHR
//SORTOUT DD DSN=MSI1390.TEST.OUTFILE1,DISP=SHR
//SORTXSUM DD DSN=MSI1390.TEST.OUTFILE2,DISP=SHR
//SYSIN DD *
SORT FIELDS=(2,10,CH,A)
SUM FIELDS=NONE,XSUM
/*
by using the above code, am facing the error message :
"ICE172A E XSUM IS NOT SUPPORTED - USE ICETOOL SELECT IF
APPROPRIATE"

Now i want the unique records in SORTOUT and the eliminated
duplicates in SORTXSUM...How can i do this?
also...we dont know the difference b/w DFSORT and
SYNCSORT...how and when to use SYNCSORT
Please suggest
