FSA - First save area

Postby LotharLochkarte » Mon Nov 29, 2010 4:35 am

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)
