PDS:- Partioned Data sets.
It is nothing but group of members under one name .
Library:- mean the base where all PS files and PDS is stored.
S v can move the member of a PDS to library........

I'm confused by this discussion. A PDS and a library in my experience are the same thing with different names. It's like car and automobile. A source library may be more frequently referred to as a PDS while a load library is more frequently referred to as a library. Either way they are both partitioned datasets designed to contain multiple, uniquely named "members".

A PDS or library may have differet attributes. Typically a source PDS has a fixed block record format (RECFM=FB), perhaps with a logical record length (LRECL) of 80 and an SMS optimized block size (BLKSIZE) of 27920. Typically a load library uses unformated records (RECFM=U) and a block size of 6160.

just my 2 cents!

regards,


tim

pds : ITS THE NORMAL ONE WHICH WE CREATE USING THE 3.2 OPTION
AND IT HOLD'S NORMAL PS MEMBERS.

LIBRARY: A PDSE (partitioned dataset extended) is called a library.......
u need to give dsntype=library while creating it.

major differ is pds will lead to SE37 after the space declared is allocated fully whereas in a pdse u wont be getting a SE37 error.

A pdse should always reside in DASD and mostly our load module library will be a pdse.....

I think that you may be getting confused with dynamic directory block allocation rather than space allocations here.

A PDSE is like any other dataset that will abend once all of its allocation has been exhausted. The fact that a PDSE is reorged automatically each time a member is deleted does tend to lessen the frequency of any space related abends.

In regular everyday usage, to most mainframe users library just means a PDS or PDSE. It's not an official term.
