#1: Editing a Linear VSAM Author: senthiled,

hi,
i have got an application to test.
The input for a program is taken from a linear vsam.
Now,for my testing.i need to change the input data.
Can i edit the linear VSAM??
I tried ..copying the linear vsam onto a flat file..edit and then again copy it into a linear vsam..but i am not getting the required output.

I doubt whether my editing itself is not correct.

Can someone help me out of this mess.

senthiled,

Do you have file-aid at your shop? If so you can edit the file using file-aid. Show us how you copied the linear cluster to seq file. Also let us know the fields you want to edit with the positions and format.

i copied the linear vsam onto a flat file using idcams as follows:

Code:

//STEP01 EXEC PGM=IDCAMS
//DD1 DD DSN=V901923.PT.ZSTR.LINEAR.STORE.EXTRACT,DISP=SHR
//DD2 DD DSN=J38W031Q.PT.ZSTR.LINEAR.STORE.EXTRACT,
// DISP=(NEW,CATLG,DELETE),UNIT=SYSDA,
// DCB=(RECFM=FB,BLKSIZE=0,LRECL=4096,DSORG=PS)
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
REPRO INFILE(DD1) OUTFILE (DD2)
/*

And how do we edit using file-aid?
We have File Aid ..but i couldn't figure out how to edit.

regards,
senthil

Senthiled,

If your shop has file-aid then it is very easy to edit files. From the file-aid main menu choose option 2 (EDIT) . On the next panel give the vsam cluster name and if you have a layout for the file specify that in the record layout section and press enter.

Check the file contents after copying to the flat file.
Editing thru File Aid is the easiest way.

I think you have given only one way - VSAM to Flat file. That looks correct. Better remove the BLKSIZE=0 parameter, let JCL do the math.

And what error message do you get with your file when you open in File-Aid ? Try browsing the dataset first (without layout).
