Hi,

How can we get the tape LRECL through CLIST.

If we can get it thru REXX also it is fine. I have tried LISTDSI and LISTC
and could not get LRECL information. Is there any other way.

Take a look at the TMS software in use at your shop.

Hi,

This may help:

Tape Management System(TMS): A program product or application that oversees tape operations. Tape management systems typically manage the enterprise's tape inventory, control user authorization to tape volumes, and request tape mounts on behalf of the user.

System people, at your site, can help you to find which TMS software is in use at your shop.

Hi,

Not sure how to do this in CLIST, but

Or you could use REXX - the basic REXX code to invoke CSI is usually included in SYS1.SAMPLIB(IGGCSIRX)

But you will need to amend it to get the bits that you want rather than the output from the way it is coded there.

Here's a link to the manual too

This posting matches exactly my requirement.
I have been trying to find the information outlined but I was unable.
Is there any code available as sample?

SYS1.SAMPLIB (IGGCSIRX) is a good place to start.

Click HERE for the documentation of CSI.

I don't see how you'll get tape DCB info using IGGCSIRX.

Depending on the TMS installed at your site, there may be methods to query the tape management catalog to find the info without actually reading the tape (as in the SYNCTOOL example). I have done this with a program for CA-1 and made it work from 3.4 using a command 'T'.

Hi,
I followed the link and the documents in SYS1.SAMPLIB (IGGCSIRX) but cannot see how to retrieve LRECL and Record Format from there.

I am afraid that I need an example.

Thanks!

Hi Anuj,

the only problem I see with your example is that entire file is going to be read, reading 1 record only sholud be sufficient.
