Seeing VSAM file data.

[Md.Imtiaz]

Hi,

I have a VSAM KSDS file with data like this:

Code: Select all

1111    abcd   Delhi
2222    efgh    Mumbai

They have used cobol program to write data into file using a copybook. Now we don't have the source code and only load module of that programme available. If I want see the fileds of the file, how I can do that as I can not know the copybook name now.

so You are telling that Your Organisation spends money in creating a file
with unknown content that nobody reads

hoping that You just expressed Yourself in a bad way,
ask around what programs read the file, and certainly looking at those programs you will find something useful

DDnames in the JCL?

Be aware that to some degree, it is not possible to determine data characteristics without a copy book or other source code. Packed decimal or binary data may be interpreted as character data (depending upon the value). X'0097994D' could be a -97994 packed decimal value, or a binary full word value of 9935181 or as the characters 'pr(' with a leading LOW-VALUE -- which way you interpret those hexadecimal digits depends upon what you treat the bytes as.

OK, re-reading and re-interpreting - perhaps 'fileds' should read as 'fields' in which case the DDNAME will only tell you the dataset name not the record layout which is perhaps what you are wanting but failed to say in a clear manner.

Yes this is what I mean. If you tell me how could I have written it I'll consider that as an example for my future posts, can you?

But now I have given up on this idea to get the copy book for this file...
