Usually you would not want to change the physical file attributes....
Which ones and why?

In a MF environment MVS,z/OS,VSE,z/VSE,VM,z/VM
unless there are changes to the application architecture/logic
there is no need to change the physical attributes of a dataset
the only thing which periodically must be checked
is the space used/allocated to the dataset

Hi,

If by physical attributes' you mean changing LRECL, Block Size etc. & if you just want to know, then use 'F33' or 'MYCOPY' in ISPF; under MVS it should work, about AS400 I'm not sure.

In my previous mail I tried to say this only icon_smile.gif .

Well, my system is very rich in house REXX/CLIST utilities & this is my first shop, so somtimes, these commands look like as if they work all across the shops, till some one from forum not says "Not working for me".

What attribute(s) do you want to change on the mainframe?

File attributes are normally defined in your COBOL code as well as the JCL that creates the file. When reading a file, the JCL typically does not need to specify the attributes.

If you describe just what you want/need to do, someone will have suggestions.

Anuj,
What you might try is to before answering, flip over to the manuals link and pull up the manual where you think the function might be....If you find it then you can provide a link with your suggestion.....

Attribute is a generic term;
You have already been told that such action is not necessary on a mainframe operating system;

until You are more specific on the attributes there answer is:
NOTHING, YOU CANNOT DO IT

Converting to different operating system means also changing the habits
and understanding first of all the capabilities of the new environment
without trying to reproduce on the new system the features of the old one

To repeat, if you explain what you need to do (on the mainframe) someone will be able to help. Most of the people here are not as/400 fluent, so while your explanation may tell an as/400 person everything they need to know, the same is not tru for us.

When you issue the CHGPFM command, what is the result on your system?

As has been mentioned, changing mainframe attributes (at least what we call attributes) is seldom donie - only when a file definition changes.
