Could you help me to solve the below scenario?

A Variable Block file having several Rec type ( Rec type 00,10,11,12... )
75th Position on the Rec type 10 having a date field in the format 20071231, I need to change all the date in the same field to 20091231.
I/P may contain multile Rec 10.

How can I do this using ICEMAN

It's not clear what you want to do.

What is the starting position of the record type (remember to count the RDW in positions 1-4)?

What is the starting position of the date you want to change (remember to count the RDW in positions 1-4)?

Do you want to change the date to '20091231' in every type 10 record, or only in type 10 records that currently have '20071231' for the date?

Code:

//TEST01    PROC                                   
//             SOUT=J                                                   
//STEP010  EXEC PGM=FILEAID                                             
//*INPUT FILE                                                           
//DD01     DD  DSN=PREFIX.BP860.STREAM.GENERIC,DISP=SHR       
//*OUTPUT FILE                                                         
//DD01O    DD  DSNPREFIX.BP860.STREAM.GENERIC,DISP=OLD       
//*            UNIT=&UNIT,                                             
//*            DCB=(RECFM=VB,LRECL=148,DSORG=PS),                       
//*            SPACE=(CYL,(1,30),RLSE)                                 
//SYSIN    DD  DSN=&PREFIX1..PARMS(TEST02),DISP=SHR                     
//SYSOUT   DD  SYSOUT=&SOUT                                             
//SYSABEND DD  SYSOUT=&SOUT                                             
//SYSABOUT DD  SYSOUT=&SOUT               
****************************
PARM : TEST02
****************************
££DD01 USER RDW=3,MOVE=(1,0,1),             
       IF=(1,NE,C'10'),WRITE=DD01O,         
       IF=(1,EQ,C'10'),                     
       MOVE=(75,C'20090401'),WRITE=DD01O     
****************************


I need to replace the FileAid utility with ICEMAN.
Rec type 10 is starting from Position 1. and the date will populate from position 75.

Here are the equivalent control cards for sort

Code:

//STEP0100 EXEC PGM=SORT
//SYSOUT   DD SYSOUT=*
//SORTIN   DD DSN=PREFIX.BP860.STREAM.GENERIC,DISP=SHR
//SORTOUT  DD DSN=your output file,
//            DISP=(NEW,CATLG,DELETE),
//            UNIT=SYSDA,
//            SPACE=(CYL,(X,Y),RLSE)
//SYSIN    DD *                                                     
  INREC IFTHEN=(WHEN=(5,2,CH,EQ,C'10'),OVERLAY=(79:C'20090401'))
  SORT FIELDS=COPY

Sreejesh ,

I don't know FileAid, but I can guess from what you posted that the answers to my questions are as follows:

5

79

In every type 10 record.

In which case, you can use this DFSORT job:

Code:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SORTIN  DD DSN=PREFIX.BP860.STREAM.GENERIC,DISP=SHR
//SORTOUT DD DSNPREFIX.BP860.STREAM.GENERIC,DISP=OLD
//SYSIN    DD    *
  OPTION COPY
  INREC IFTHEN=(WHEN=(5,2,CH,EQ,C'10'),OVERLAY=(79:C'20090401'))
