Why we are using LABEL RECORDS ARE STANDARD in files?

Hi pradeep,

In mainframe printers we have standard header and trailer label which give information about the record creation date , expiration date and so on. If we give LABLE RECORDS ARE STANDARD then the printers will print with headers and trailers label with details of records.

Thanks

Hi,

I think we use LABLE RECORDS ARE STANDARD when ur output is a standard disk file.
if ur output is going to be a printer then u use label records are ommited.

correct me if iam wrong.

Hi Pradeep,

What Machswap says is true except that the labels are used for both disk and tape datasets.

In the more recent COBOL releases this option is no longer required. If it is used it's treated as a comment.

Think of it as an appendix. :)

Hi,

I think for printers there are no LABEL RECORDS.

So, we might like to use LABEL RECORDS ARE OMMITTED for output going to the printer.

Offcourse, with new cobol compilers in place, LABEL RECORDS clause is no longer required.

Thank,

I repeat, it's no longer required. Just keep it in mind if you have to use it on older hardware. As I recall, it specified std, non-std or no labels for tape, std for disk.

I know it wasn't required in cobol2, maybe before.

hi,
by using the label records we can access the file in inut or output mode even though it is specified in any mode,header and trailer label specifies that the file being processed is correct one or not.

As of my knowledge, LABEL RECORDS ARE STANDARD can be used to verify that, is it accessing the correct file records are not. The length could be the 80bytes and it will be created while writing into the file and it will verify while reading the records from the file.
