Dynamic Splitting of files

Postby ratheesh2011 » Tue Mar 22, 2011 9:14 am

Hi ,

I have a requirement as below.

My input file looks like below

line-1
line-2
line-3
$$$
line-4
line-5
$$$
line-6
line-7
line-8
line-9
$$$
line-10
line-11
line-12
$$$

I have to split this file into multiple files,
FIle-1
----------
line-1
line-2
line-3

FIle-2
----------
line-4
line-5

FIle-3
----------
line-6
line-7
line-8
line-9

FIle-4
----------
line-10
line-11
line-12

The input file can have many sets of records ( here it is 4 sets ) , it can be dynamic. The file has to be splitted by the delimiter '$$$' at the 1st 3 chars.
Please help me to get a solution for this.

Thanks
Ratheesh

And I suppose there can be up to 2000 output files as per the topic on the other board?
The problem I have is that people can explain things quickly but I can only comprehend slowly.
Regards

Nah, 2000? Then read each, and know that you read once and only once, of those and do "something". Just sounds silly. You'll have to make your output more complicated to keep your later inputs manageable. Or do it on Unix/PC so we someone else has to wonder what you are doing...

Do you have a real requirement? If you explain, perhaps we can suggest something. Although perhaps we won't if you're already getting other people to look at this for you (you think!).

Can I suggest the dataset names?

After your standard high-level stuff, put "HAHA.GOTYOU.STORAGE.TEAM.Vxxxxxx". Where Vxxxxxx is unique, per write if possible in SORT, and should give them a good scare that more are on the way. Make them GDGs as well.

If you want to screw up OPS instead, put them all to tape. Leave them as GDGs if you think the storage people deserve a little something.

SyncSort cannot dynamically generate the DD statements required for the output files.

Thanks for your replies.
Or I want to get my input to be splitted into 2 files as below,

File-1
----------
line-1
line-2
line-3

File-2
-----------
line-4
line-5
$$$
line-6
line-7
line-8
line-9
$$$
line-10
line-11
line-12
$$$

I think we can make possible this by WHEN=GROUP. But I don't know how. Please help me to get this resolved.

This will split the input into 2 files:
//SORT1  EXEC PGM=SORT
//SORTIN   DD DISP=SHR,DSN=INPUT.FILE.FB80               
//SORTOF01 DD SYSOUT=*
//SORTOF02 DD SYSOUT=*
//SYSOUT   DD SYSOUT=*
//SYSIN    DD *                                                 
  INREC IFTHEN=(WHEN=GROUP,END=(1,3,CH,EQ,C'$$$'),PUSH=(81:ID=1))
  SORT FIELDS=COPY                                               
  OUTFIL FILES=01,INCLUDE=(81,1,ZD,EQ,1),BUILD=(1,80)           
  OUTFIL FILES=02,SAVE,BUILD=(1,80)                             
/*       

SORTOF01 contains the following records:
LINE-1
LINE-2
LINE-3
$$$   

SORTOF02 contains the following records:
LINE-4
LINE-5
$$$   
LINE-6
LINE-7
LINE-8
LINE-9
$$$   
LINE-10
LINE-11
LINE-12
$$$
