Mainframe Question What is hlq in mainframe? Answer Raj Pandit answered High-level qualifiers HLQ permit you to associate an application's configuration data set with a particular job name or TSO user ID, or permit you to use a default configuration data set for the application. Here's the output for our dataset: We can see our two records one shaded in orange, one in blue.

But wait. Our block is bytes long, but we've defined the blocksize of our dataset as So what's going on? We only have two records in our dataset. So, the block is bytes, holding both our records. The remaining bytes of our block are reserved, and used when we add more records. We can see that the first record, although only 20 bytes long, is from offset x'' to x'00FF' of our block: it uses up bytes: our fixed record length.

We can see our second record start at offset x'', and finish at x'01FF'. So our two records are in the same block. How can this be? Every record written to this dataset must be bytes or less in length. But if the record we are writing is only bytes, then it written to disk as a byte block a 'short' block.

Let's prove this. We wrote the same two records as above: one 25 bytes long, one bytes long. Here's the output:. The first record is in the first block, of length x'14' 20 bytes. The other is in a different block of length x'FA': bytes.

You can write a program to read, then update a record. Some utilities like IBM Filemanager can also help. You can update the contents only. If you update a record with a longer record, it is truncated.

If it's shorter, it is padded. This makes them ideal for load modules and project objects. There are several records doing different things. Some hold information about external references in brown , others have details about the binder version, and when it was bound purple.

And of course, there are the records with the actual module text blue. You can see that these records are of differing lengths, and remember that each is a different block.

Rather, we simply recreate the module every time it is bound. Today, there are better options around such as VSAM linear datasets. Nothing special: just reads every record, and displays the result. Here's what we see with a hexadecimal display below the contents of the record :.
