IBM Mainframe Forum

Hi,

does somebody know where I can find a description of the content of the FSA, the first save area, that is pointed to by (for example) TCBFSA?

Thanks!

And by the way: Is there a reason why my registration on ibmmainframes.com is still not activated? I filled out the form a week ago or so.

The "first" save area (the save area that TCBFSA points to) has the same format at any other save area. I believe this save area is the old OS/360 72 byte save area, not the larger save area properly required for programs that use 64-bit registers or or the still larger save area required for programs that receive control in AMODE 64. This link may answer your questions.

Thank you, the link really helps!

At the moment I am a little bit confused, where I can find information about some control blocks... I googled a lot but I wasn't able to find a link with the description of the IMS control block DFSECP for example.

(Honestly, I also searched for FSA but didn't find your link)

Well, I knew where to look; I did't really have to "search" very hard! I did a Google search for "z/os save area" and came up with several promising links.

As for DFSECP; you should try the IMS area.

Searching for "DFSECP" didn't yield useful results...

Could it be possible that the DFSECP control block is antiquated?

I tried to get this program running in our IMS environment:
http://ims.gse.org.uk/archive/gse_files/imsid.txt

But the compiler doesn't even find the DFSECP DSECT.

Do you know if there is a way to see all available DSECTs in our environment?

Thanks!

Ok, forget my last post...

I have found it (in one of our system libs)
