HI,
There is a requirement of converting a julian date in a file to the format MM-DD-YYYY through jcl.

In the file it is in the format +1999016 which is to be converted to
01-16-1999.
Can anyone help me by providing any sort card for doing this.

If I read correctly, the SORT which Frank has written in that post covers from 1950 to 2049...

Yes, I am pretty sure that You, I, almost everybody will read correctly, but there are always exceptions

quoting the linked solution
Code:
* If yy > 49, convert Z'yyddd' to X'00yydddC'       
  INREC IFTHEN=(WHEN=(1,2,ZD,GT,+49),               
    BUILD=(X'00',1,5,ZD,TO=PD,LENGTH=3)),           
* If yy <= 49, convert Z'yyddd' to X'01yydddC'     
   IFTHEN=(WHEN=NONE,                               
    BUILD=(X'01',1,5,ZD,TO=PD,LENGTH=3))           
* Convert to X'00yydddC' to Z'19yymmdd'.           
* Convert to X'01yydddC' to Z'20yymmdd'.           
  OUTREC IFTHEN=(WHEN=INIT,BUILD=(1,4,DT1)),       
* Convert to Z'ccyymmdd' to C'mm-dd-ccyy'.         
   IFTHEN=(WHEN=INIT,                               
    BUILD=(5,2,C'-',7,2,C'-',1,4))                 


the TS complains that his date is not a short julian(YYDDD) , but a long one (CCYYDDD),
and does not realize (he is too lazy to) that it' s enough to skip the first four steps of the posted solution

edited to correct a glitch
I was misled by the comments in the solution ...
still, looking at the sort manuals it would have been easy to find the glitch and fix accordingly,
also a quick and dirty forum search for dt1 would have taken the ts to ...
www.ibmmainframes.com/about7034.html
which is the perfect complement to get the solution

quoting the linked solution
Code:
 OPTION COPY
* Convert X'19yyddds' to X'00yyddds'.
* Convert X'20yyddds' to X'01yyddds'.
  INREC FIELDS=(1:1,1,CHANGE=(1,X'19',X'00',X'20',X'01'),
    NOMATCH=(X'02'),2:2,3)
* Use SMF date format (DT1) to convert X'0cyyddds' to Z'yyyymmdd'
* and P'yyyymmdd'.
  OUTREC FIELDS=(1,4,DT1,X,1,4,DT1,TO=PD,LENGTH=5)


what bothers me is that people just want to be spoon fed and lack completely the ingenuity to find something themselves

take the first part of solution 2 and the second part of solution 1

another hint...
the first part of solution 2 transforms the CCYY in a forma tsuitable for the DT1 format
second part of solution 1 formats the DT1 produced result to the format asked for by the TS

anyway, again, a forum search would have provided the TS with all the info needed,
and would have made him gain a bit of experience in problem solving and solution research

... solution research is always an iterative process

Enrico, did you assume that his catch rate is allowable under the EU fishing quota limitations.

all depends on the price of the daily fishing pass

for forums answers the process is a bit murky..
we pay for the pass and they get the fish icon_wink.gif

Hi ,

I agree with Enrico comments. But if your input in ZD format then following code should work
Code:

   OPTION COPY                                         
* IF CC =19, CONVERT Z'CCYYDDD' TO X'00YYDDDC'           
  INREC IFTHEN=(WHEN=(1,2,ZD,EQ,+19),                   
                BUILD=(X'00',3,5,ZD,TO=PD,LENGTH=3)),   
* IF CC =20, CONVERT Z'CCYYDDD' TO X'01YYDDDC'           
        IFTHEN=(WHEN=NONE,                             
                BUILD=(X'01',3,5,ZD,TO=PD,LENGTH=3))   
* CONVERT TO X'00YYDDDC' TO Z'19YYMMDD'.               
* CONVERT TO X'01YYDDDC' TO Z'20YYMMDD'.               
  OUTREC IFTHEN=(WHEN=INIT,BUILD=(1,4,DT1)),           
* CONVERT TO Z'CCYYMMDD' TO C'MM-DD-CCYY'.             
         IFTHEN=(WHEN=INIT,                             
                BUILD=(5,2,C'-',7,2,C'-',1,4))         


Its not an optimal solution But it will provide your output

Neena,

If you have the Nov, 2009 DFSORT PTF, you can do what you want with a DFSORT job like the following:

Code:

//S1    EXEC  PGM=SORT                       
//SYSOUT    DD  SYSOUT=*                     
//SORTIN DD *                               
+1999016                                     
+1999001                                     
+2000001                                     
//SORTOUT DD SYSOUT=*                       
//SYSIN    DD    *                           
  OPTION COPY                               
  INREC BUILD=(2,7,Y4T,TOGREG=Y4W(-))       
/*


SORTOUT would have:

Code:

01-16-1999   
01-01-1999   
01-01-2000   


If you don't have that PTF, ask your System Programmer to install it. For more information on the PTF, see:

Here is a SyncSort for z/OS 1.3 job that will produce the requested output:
Code:
//SORT1 EXEC PGM=SORT,PARM='CENTWIN=80'
//SORTIN  DD *                             
+1999016                                   
//SORTOUT DD SYSOUT=*                     
//SYSOUT  DD SYSOUT=*                       
//SYSIN   DD *                               
  INREC BUILD=(4,5,Y2T,DT=(MD4-))         
  SORT FIELDS=COPY
