Scenario - Create three output files like below -

dept1 records to file1
dept2 records to file2
records other than dept1 to file3

Input File - MATEPK.SORT.INPUT01 - FB file of 80 length

----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8
00001     student1           dept1          560

Explaining Example -

1. SORT FIELDS=(1,5,ZD,A) - sort all outputs in ascending order based on the ZD value from 1 to 5 positions.
2. OUTFIL FNAMES=OUTPUT1,INCLUDE=(30,5,CH,EQ,C'dept1') - All the records marching with "dept1" from the 30th position of length 5 will be copied to output1 file.
3. OUTFIL FNAMES=OUTPUT2,INCLUDE=(30,5,CH,EQ,C'dept2') - All the records marching with "dept2" from the 30th position of length 5 will be copied to output2 file.
4. OUTFIL FNAMES=OUTPUT3,OMIT=(30,5,CH,EQ,C'dept1') - All the records marching with "dept1" from the 30th position of length 5 will be ignored and remaining all records will be copied to output3 file.
