Hello All,

I have a scenario where i need to copy date from a file1 to the header record of file2.

Input file1 - LRECL/RECFM - FB/1900

This file contains only one record with processing date at position 1 of length 8.
Code:
----+----1----+----2
09/16/11

Input file2 - LRECL/RECFM - VB/334

First record is the header record and can also be found by the value 'PROCESS' in position 9 of length 7.
Code:
----+----1----+----2----+----3----+----4
Date of process :
Data1
Data2
Data3


Expected output file - LRECL/RECFM - VB/334
Code:
----+----1----+----2----+----3----+----4
Date of process :09/16/11


Any pointers would be helpful.

Code:
SYNCSORT FOR Z/OS  1.3.0.2RI

since you have only one record in the file containing the date,
a modification of this:
ibmmainframes.com/viewtopic.php?p=106139&highlight=append#106139
and using IFTHEN to find the header in you second step probably would work.

I have one more requirement here to repeat the header whenever there is a key change.

Input file -
Code:
----+----1----+----2----+----3----+----4----+----5----+----6----+----7
Date of process :09/16/11                        DATA11 123456798           
Data11
Data12
Data13
Data21
Data21
Data23
Data31
Data32
Data33

Output file -
Code:
----+----1----+----2----+----3----+----4----+----5----+----6----+----7
Date of process :09/16/11                        DATA11 123456798           
Data11
Data12
Data13
Date of process :09/16/11                        DATA21 123456798           
Data21
Data21
Data23
Date of process :09/16/11                        DATA31 123456798           
Data31
Data32
Data33

Both the input and output files are LRECL/RECFM - VB/334.

Any pointers on this one.

Hi bill,

Thank you for the quick response. Actually the solution did work for writing a new header, but mine is to repeat the existing header with few modifications.

Please let me know if you come across any such scenario.

Sorry, I took this too literally I suppose, didn't check against the data provided and notice the one character in the middle of the data that is different :-)

I thought you might get to a different problem, being how to get the basic header information, rather than the "break" key, which should be fine with this.

Can you post what you got as your solution for the first part?

Hi,

you might use this as a starting point
Code:

Bill,

I am using below code to extract the date as you suggested.
Code:
//S1 EXEC PGM=ICETOOL                                                 
//DFSMSG DD SYSOUT=*                                                 
//TOOLMSG DD SYSOUT=*                                                 
//IN1      DD DSN=input file1...FB/1900
//IN2      DD DSN=input file2...VB/334         
//TEMP     DD DSN=temporary file...FB/80                                       
//OUT      DD DSN=output file2...VB/334                                                 
//TOOLIN   DD *                                                       
 COPY FROM(IN1) TO(TEMP) USING(CTL1)                                                                       
 COPY FROM(IN2) TO(OUT) USING(CTL2)                                   
//*                                                                   
//CTL1CNTL DD *                                                       
  OUTFIL BUILD=(1:C'  INREC IFTHEN=(WHEN=(8,1,CH,EQ,C''1''),',/,     
               C'      OVERLAY=(18:C''',1,8,C'''))',80:X)             
/*                                                                   
//CTL2CNTL DD *                                                       
  SORT FIELDS=COPY                                                   
//    DD DSN=temporary file


Gerry,

This file is getting received from other application and they are populating values after the 100th byte which wont be constant in the header record. So building as mentioned wont work. I should have mentioned it before icon_redface.gif. One more information missed is there can be only three type of records that can be present in the dataset (DATA1, DATA2, DATA3).

I tried using the below code to repeat the header records...But the issue here is the dataset does not always contain all the datatype records.

Code:
OUTFIL IFTHEN=(WHEN=(13,7,CH,EQ,C'PROCESS'),         
BUILD=(1,334,/,1,53,54:C'DATA21',60,275,/,1,53,54:C'DATA31',60,275))                 
SORT FIELDS=(1,3,CH,D)

I meant to say after the 100th byte the values are not fixed. It varies daily...

Was able to achieve the output using symnames by splitting the header record as shown

Code:
  SORT FIELDS=COPY                                           
  INCLUDE COND=(5,4,CH,EQ,C'DATE')                           
  OUTFIL BUILD=(C'HEAD1,''',5,49,C'''',80:X,/,               
                C'HEAD2,''',60,70,C'''',80:X,/,             
                C'HEAD3,''',130,70,C'''',80:X,/,             
                C'HEAD4,''',200,70,C'''',80:X,/,             
                C'HEAD5,''',270,64,C'''',80:X),VTOF         


If you take a look at the code HEAD2/3/4/5 are just the breakup of the record becoz of the limitation of SYMNAMES record length. Is there any way we can assign only one symbol for the record starting from position 60 - 334 by providing any conituation character ?

Here the header record is rebuilt whenever the data type varies.

Code:
  SORT FIELDS=COPY                                                 
  OMIT COND=(5,4,CH,EQ,C'DATE')                                     
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(335:SEQNUM,4,ZD,RESTART=(5,5))) 
  OUTFIL IFOUTLEN=334,IFTHEN=(WHEN=(335,4,CH,EQ,C'0001'),           
         BUILD=(1,4,HEAD1,5,6,HEAD2,HEAD3,HEAD4,HEAD5,/,1,334))     


Thanks everyone for your help.
