One of the pleasures of Google is the ability to get help on almost anything IBM mainframe related by searching for something like:
TSO REXX POS
and you'd get back a pointer to the page in the online library to the POS function within the first five or so Google hits. Given that the z/OS 2.1 doc has been out there for a very long time, almost all of the "hits" refer to the z/OS 2.1 knowledge center.
IBM took down all these books in the last couple of days and now all of these hits have been turned to $hit:
Documentation for z/OS V2.1.0 is no longer available in IBM Knowledge Center.
While the product version and release remains in service, you can find information in the following formats:
Individual PDFs for downloading: https://www.ibm.com/servers/resourcelink/svcoo100.nsf/pages/zosv2r1-pdf-download?OpenDocument
z/OS V2R1 Adobe Indexed Collection (all PDFs with full text search via the free Adobe Acrobat Reader): http://publibz.boulder.ibm.com/zoslib/pdf/zosv2r1pdfcollection.zip
IBM Knowledge Center plugins for downloading (for use with IBM Knowledge Center for z/OS): http://publibz.boulder.ibm.com/zoslib/SSLTBW_2.1.0_4KC.jar.
For information about current releases of this product see http://www.ibm.com/support/knowledgecenter/SSLTBW/welcome.
More information and resources are available at the IBM z/OS Internet Library: https://www.ibm.com/servers/resourcelink/svcoo100.nsf/pages/zosinternetlibrary?opendocument.
Now, this isn't IBM's fault. However, taking the same search to the z/OS 2.2 KC main page gives nothing of value for someone looking for the POS (ironic, huh?) function (the search was TSO REXX POS):
- The TSO command environment
- Host command environments for z/OS UNIX processing
- TSO commands, CLISTs, and REXX EXECs
- Using TSO subcommands from a TSO CLIST or REXX exec
- REXX ADDRESS TSO support requirements
Here's Google's #1 hit (that's as far as you have to go) for TSO REXX POS:
POS (Position) - IBM
POS (Position) z/OS TSO/E REXX Reference SA32-0972-00 ... (See also the INDEX and LASTPOS functions.) Returns 0 if needle is the null string or is not found ...
To curtail a possible rathole on this discussion, please don't suggest adding "z/OS 2.2" to the Google search. It doesn't help. The Googler simply returns a similar set of hits and says it couldn't find "2.2".
POS (Position) - IBM
z/OS TSO/E REXX Reference ... returns the position of one string, needle, in another, haystack. (See also the INDEX and LASTPOS functions.) Returns 0 if ...
Missing: 2.2 <==== weird for the most likely hit, no?
I'd be glad to entertain suggestions on how to better negotiate Google (use Bing?) or make the IBM KC site return more intelligent results. Whatever happened to Watson?
