Limit the display of records while copy.

[Seema Jain]

Hi,

Some of the files are on tape and have a very huge volume of data. I am trying to bring it on disk to see the records. Could anyone tell me how to limit the display of records on disk while copying from tape. I do not want take copy of al the data, I just want to see some sample data. I am using the following JCL:

Code: Select all

//STEP1 EXEC PGM=SORT 
//SYSOUT DD SYSOUT=* 
//SORTIN DD DSN=my.tape.dataset,DISP=SHR 
//SORTOUT DD DSN=my.disk.dataset, 
// DISP=(,CATLG,DELETE), 
// UNIT=WORK,SPACE=(CYL,(50,100),RLSE) 
//SYSIN DD * 
OPTION COPY 
/*

Can anyone please guide me on this. Thanks in advance.

There are a number of ways. You can look at, amongst others to which these should lead you in the manual, STOPAFT and SAMPLE.

Thanks for your help William Collins. This JCL has worked for me

Code: Select all

//STEP1 EXEC PGM=SORT 
//SYSOUT DD SYSOUT=* 
//SORTIN DD DSN=my.tape.dataset,DISP=SHR 
//SORTOUT DD DSN=my.disk.dataset, 
// DISP=(,CATLG,DELETE), 
// UNIT=WORK,SPACE=(CYL,(50,100),RLSE) 
//SYSIN DD * 
OPTION COPY 
STOPAFT=500
