Hello,

I need to compare 2 records of the same file(sorted in ascending order), If first 4 bytes of the records are same and 5th byte in first records is blank and 5th byte in second records is not spaces, then I need to write output record with first 4 bytes and 5th byte(which not spaces in the second record). example given below. If there are no duplicate records based on first 4 bytes then that record should be written to output file as it is.

Input file:
----------
aaaa
aaaaM
bbbb
cccc
ccccM

Output file should be:
-------------------------
aaaaM
bbbb
ccccM


We are using both DFsort and ICETOOL in our system.


Regards,
Chinnadu

chinnadu,

Use the following DFSORT/ICETOOL JCL which will give you the desired results
Code:

//STEP0100 EXEC PGM=ICETOOL                           
//TOOLMSG  DD SYSOUT=*                               
//DFSMSG   DD SYSOUT=*                               
//IN       DD *                                       
AAAA                                                 
AAAAM                                                 
BBBB                                                 
CCCC                                                 
CCCCM                                                 
DDDD                                                 
DDDD                                                 
//OUT      DD SYSOUT=*                               
//TOOLIN   DD *                                       
  SELECT FROM(IN) TO(OUT) ON(1,4,CH) FIRST USING(CTL1)
//CTL1CNTL DD *                                       
  SORT FIELDS=(1,4,CH,A,5,1,CH,D)                     
//*
