BFREED is a demo version of BFree from Allegro Consultants, Inc.

BFree is used to save Extent B-Tree entries needlessly used by TurboIMAGE.

In addition, BFree can report information about the Extent B-Tree table.

BFree currently has two different strategies it employs to save
Extent B-Tree table entries.  These are referred to as BFree.1
and BFree.2.  BFree.1 saves one entry per opened jumbo dataset.
BFree.2 saves two entries per opened database.

BFREED reports both kinds of savings together.

To install BFREED:

   :newacct allegro, mgr
   :altacct allegro;cap= &
      AM,AL,GL,DI,CV,UV,LG,PS,NA,NM,CS,ND,SF,BA,IA,PM,MR,DS,PH
   :altacct allegro; access = (r,x,l:any; w,a:ac)
   :altgroup pub.allegro; cap = BA,IA,PM,MR,DS,PH
   :altgroup pub.allegro; access = (r,x,l:any; w,a,s:ac)

and, put a password on the ALLEGRO account.

Upload BFREED to BFREED.PUB.ALLEGRO.

Usage:  RUN BFREED.PUB.ALLEGRO

The most used BFREED commands are probably:

   INFO     ... what VSM tables are filling up?
   STATUS   ... report how many entries could be saved

                 MAXERRors # |
                 noPAGING | RESET | SET |
                 noVerbose | WIDTH #

   Allows you to SET (or RESET) various options:
      HEX         ... display KSOs as hex values
      MAXERRORS # ... specify the maximum number of errors
                      that the VSOD command may encounter
                      before it terminates.  (default: 10)
                      A value of 0 means "no limit".
      PAGING      ... for paginated output
      WIDTH       ... terminal width
      80          ... WIDTH 80 *and* the HP escape
                      sequence to set the terminal
                      to 80 columns is sent.

      132         ... WIDTH 132 *and* the HP escape
                      sequence to set the terminal
                      to 132 columns is sent.

   The number of lines per output page defaults to 24,
   and can be overridden by "SETJCW LINES #" prior to
   running BFree.

STATUS  [QUICK]  [SETVAR]

   The STATUS commands reports the number of in-use Extent B-Tree
   entries.

   The SETVAR (or "JCW") option causes STATUS to create some CI
   variables:

      BFREE_ENABLED  ... true/false if any BFree savings is
                         enabled

      BFREE_ENABLED1 ... true/false if BFree.1 is enabled
      BFREE_ENABLED2 ... true/false if BFree.2 is enabled

      BFREE_PERCENT_FULL ... how full is the Extent B-Tree table

      BFREE_SEEN     ... # of Extent B-Tree entries in use

      BFREE_SAVED    ... # of entries saved by BFree

      BFREE_SAVABLE  ... # of entries savable if BFree
                         had been enabled earlier.

   The QUICK option causes STATUS to just report the status
   of BFree savings mode.

---------------------------------------------------------------

The Extent B-Tree table entries are officially called "nodes",
and each node has up to 4 entries in it.

However, many people in the HP 3000 community refer to the
top-level items in the Extent B-Tree as "entries" instead of
"nodes".  BFree also refers to them as "entries" to avoid
confusion.
