Hi,

I have the following input file

Code:

Rec type    Rec seq
1111         A
1111         B
1111         C
1111         D
1111         E
2222         A
2222         B
2222         C
2222         D
2222         E


I have the following output after the sorting it with Rec type acending and Rec seq descending

Code:

1111         E
1111         D
1111         C
1111         B
1111         A
2222         E
2222         D
2222         C
2222         B
2222         A


But I want the output file to be like

Code:

1111         E
1111         B
1111         D
1111         C
1111         A
2222         E
2222         B
2222         D
2222         C
2222         A


I want the records with record seq 'B' to come after record seq 'E' all the time. The rest of the records should follow the sorted order of record seq descending. Is it possible to sort this way? All suggestions are welcome.

Thank you
JSP

JSP,
You can use the following code. (Change the column position for the Record sequence).

Code:

//STEP     EXEC PGM=SORT
//SYSIN    DD *
 ALTSEQ CODE=(C4C2,C2C4)
 SORT   FIELDS=(1,1,AQ,D)
/*
//SORTIN   DD *
A 1
B 2
C 3
D 4
E 5
/*
//SORTOUT  DD SYSOUT=*
//SYSOUT   DD SYSOUT=*


The ALTSEQ will temporarily override the collating sequence. Thus, C4 (D) will 'become' C2 (B) and vice versa.
