Hi,

i have a flat file with a few million records..i need to copy records corresponding to a few 1000 accounts ...is there any way of doing this other than using the sysin stream..?

my jcl is something like this:
Code:

//COPYFILE EXEC PGM=FILEAID                                     
//SYSUDUMP DD SYSOUT=H                                         
//SYSTOTAL DD SYSOUT=*                                         
//SYSLIST  DD SYSOUT=*                                         
//SYSPRINT DD DSN=DNW.NBS8P.TAPEDATA.MIM2TRY,DISP=SHR         
//DD01     DD DSN=DNW.NBSCAT.DNWBA701.NMCGEN.TEMP2904,DISP=SHR
//OUT3     DD DSN=DNW.NBS8P.TEMP2904.TESTOUTZ,DISP=MOD         
//SYSIN    DD *   
$$DD01 USER  IF=(1,EQ,C'23420300025712'),                   
             ORIF=(1,EQ,C'23420300025733'),                     
             ORIF=(1,EQ,C'23420300024700'),WRITE=OUT3           
//*                                                             


DD01 contains about a million records. my problem is that the SYSIn stream will be really large in case i want to specify a 1000 ORIF statements.

is there any way i can use a file which contains the sysin statements and specify this file instead of the sysin stream? this would save a lot of time since such a file can be easily generated.

You can code all your sysin statements in a file and point that dsn name to the sysin dd name.

Code:

//SYSIN    DD DSN=YOUR CONTROL CARDS,DISP=SHR


Since your sysin cards are close to 1000 , you may to need to use the parm MAXENT to avoid any kinds of abends.

Code:
 
$$DD01 USER MAXENT=1000,IF=(1,EQ,C'23420300025712'),
  ...


The other option is to code all the account #'s to be extracted in a seperate file and you can run a batch file-aid COMPARE and extract the records.

If the records are unique, you can extract the desired records from the input file using SORT

Hope this helps...

Cheers
