Hi,

I have a file in the following format:
Code:

USERAL    012CD  ABDC
          00B1    XYZ
          012D7  PQRS
USERTT    00MN   WER
          00KB   KRISHNA
          00BS   RAM   


USERAL and USERTT are aligned
Requirement:
If the following record is inserted in the file at the end
Code:

USERAL    1214  VISWA 

On sorting the file, the file should look like this:
Code:

USERAL    012CD  ABDC
          00B1    XYZ
          012D7  PQRS
USERAL    1214  VISWA
USERTT    00MN   WER
          00KB   KRISHNA
          00BS   RAM

Kindly let me know if this can be possible through DFSORT? Any solutions will be really helpful

Thanks
Viswanathan

vishysblue,

Concatenate the last record that you want to append to your SORTIN. You can very easily push the header using the new WHEN=GROUP function of DFSORT available with z/OS DFSORT V1R5 PTF UK90013 (July, 2008) like this:

I assumed your input to be FB and LRECL 80
Code:

//STEP0100 EXEC PGM=SORT                                       
//SYSOUT   DD SYSOUT=*                                         
//SORTIN   DD *                                                 
USERAL    012CD  ABDC                                           
          00B1    XYZ                                           
          012D7  PQRS                                           
USERTT    00MN   WER                                           
          00KB   KRISHNA                                       
          00BS   RAM                                           
//         DD *                                                 
USERAL    1214  VISWA                                           
//SORTOUT  DD SYSOUT=*                                         
//SYSIN    DD *                                                 
  OPTION EQUALS                                                 
  INREC IFTHEN=(WHEN=GROUP,BEGIN=(1,1,CH,NE,C' '),PUSH=(81:1,6))
  SORT FIELDS=(81,6,CH,A)                                       
  OUTREC BUILD=(1,80)                                           
/*


If you don't have the July, 2008 PTF installed, ask your System Programmer to install it (it's free).

For complete details on the new WHEN=GROUP and the other new functions available with PTF UK90013, see:
