IBM Mainframe Forum

Hello
I have one query Could you please help

*We used to add dataset name in LINKLIST inorder to concatenate those Datasets into SYS1.LINKLIB Am i right ?

* We used to add dataset name in LPALIST inorder to concatenate those Datasets into SYS1.LPALIB Am i right ?

What is the use of it where it will be useful ?

It may be a basic question please answer me ?

Thanks & Regards,
Bharath

The LINKLIST and LPALIB (Link Pack Area LIBrary) are related concepts. The LINKLIST is a collection of libraries, established during the IPL, that contain system and user load modules. Any program in the LINKLIST does NOT require a JOBLIB or STEPLIB to point to the load library -- the system can find such programs without any JCL statements. The LPALIB basically contains read-only programs (which may system or user load modules) that are reenterable.

Thanks a lot Robert

The Datasets concatenated inside LPA can be shared by n number of tasks(At the Same time)

And It(LPA) contains load modules and System modules and program in it does NOT require a JOBLIB or STEPLIB to point to the load library

Am clear with LINKLIST From your post

Could you please elaborate LPA the same and what is the difference between LINKLIST AND LPA

Thanks in Advance

And the relevancy of this post to the forum rules?

To which the TS replied in a now no longer private message:

I'll count to 10, very slowly...

The LPALIB basically contains read-only programs (which may system or user load modules) that are reenterable.

Does Datasets concatenated inside LPA can be shared and accessed by by n number of tasks(At the Same time)

and is it the only difference between LPA and LINKLIB ?

The LINKLIST and LPALIB do not apply to "data sets". They only reference load libraries -- PDS or PDSE data sets that contain compiled programs. And while there are some differences between LINKLIST and LPALIB programs, these differences are generally considerably beyond the scope of this forum -- "beginners and students" would not need to know such differences. Both reside in common memory of the system so all address spaces ("tasks" as you put it) have access to them (at the same time if needed).

Thanks a lot Robert for your time
