Re: Virtual SHARE Ageenda

In TSS/360, VPAM datasets can have both sequential and index sequential 
members; you can read and write withing a member either sequentially or by key, 
including inserting a new record between existing members. VIPAM is a 
colloquial term for a VPAM dataset containing VIS members. From the 
documentation:

 Three special Data Management Access methods -- the virtual Access
 Methods (VAM)-- have been provided with TSS. They are specifically
 designed for a time-sharing environment and are used to read and write
 data to and from direct access storage devices. For all three of the
 VAM access methods, the data set management (for example, formatting)
 is performed in virtual storage -- using virtual addresses that are
 part of the user's virtual storage address space -- although physical
 device management (e.g., I/O) is performed by system programs in
 resident storage.  Each access method provides access and processing
 capabilities for data sets organized in a specific manner.

  * sequentially (Virtual Sequential Access Method -- VSAM)

  * indexed sequential (Virtual Indexed Sequential Access Method --
VISAM)

  * partitioned (Virtual Partitioned Access Method -- VPAM)

 In TSS, data sets organized for processing by one of the virtual
 access Methods are generally referred to as VAM data sets.

and

 Partitioned Organization
  A data set with partitioned organization has elements, or
  members, that are other data sets; these elements are in either
  sequential or indexed organization.

What is the logical difference between VPAM (found it in a TSS360
description) and PDSE except PDSE is an add-on (my opinion of the
decision maker who decreed that PDSE or at least a read-only subset
didn't need to be available for SYS1.PARMLIB, SYS1.NUCLEUS and
SYS1.LPALIB is complete contempt)?

Re FBA, they did it for other systems, and TSS/360 used page formatted volumes 
for everything except compatibility volumes, so from a technical perspective 
it's a no brainer, although direct use of SCSI DASD might make more sense these 
days. Politically, it's a thorny issue. I'd love to see them extend VSAM to the 
level of TSS while they're at it, e.g., VIPAM.

Subject: Virtual SHARE Ageenda

The virtual SHARE in August will cost only 199 USD for members, 399
USD for non-members.  There will obviously be no travel expenses if
you have access to high enough speed Internet.  There are
opportunities for Birds Of a Feather sessions.  If I sign up, I might
try to set up a BOF session on COBOL 2014, some of the very useful
features and whether they are 20 - 40 years too late because
organizations have already implemented work-arounds and won't revisit
the code?  I also am interested in discussing whether making the
effort to have z/OS handle FBA devices for FBA data sets (all VSAM,
PDSEs, page data sets, etc.) would be worthwhile and creating FBA
equivalents of SYS1.NUCLEUS (combine it with the IPL text?) SPOOL
etc.?

The schedule which gives the dates and shows the slots for BOF
sessions.

Re: Virtual SHARE Ageenda

At $199, I signed up using personal money. At that price, and even if I can 
only join a subset, it's a no-brainer opportunity.
