UPGRADING FROM PB911221 or PB920224 to PB920430

There are major advances in this version of PB, but all of your
present data can be "brought forward" to the new version.

I suggest that you start your PB.CFG over from scratch, since
some entries have been made redundant, and in most cases the
defaults are VERY STRONGLY SUGGESTED. You can start with the
PB.CFG on the distribution disk, and then gradually add the
customisations that you really need. As you add them, please
check the current documentation to find out their exact
effects. Please take the time to do this.

It is especially important that you review your use of ALIAS/MYADDR
and BLOCKFTYPES in the light of the new select equation processor
which automatically will set mail to ALIAS/MYADDR as priority and
messages to ALL of less than 10000 bytes to automatic. This 
behaviour is in the built-in equations. For interest, I have
duplicated the built-in equations in the example PB.EQN file
so that you can begin modifying. To activate PB.CFG, just place
a line 

select pb.eqn

into PB.CFG.

(The built-in equations are invoked if there is NOT a "select" line 
in PB.CFG.)


SLIST.DAT migrates unmolested.

PFHDIR.PFH is replaced by a series of smaller .PFH files. A utility
called PFHSPLIT.EXE is provided for this purpose. Run PFHSPLIT.EXE
without arguments and it will split your PFHDIR.PFH up into a bunch
of files starting with PB__0000.PFH. You can then delete PFHDIR.PFH
or put it somewhere for safe keeping.

PFHDIR.HOL migrates unmolested.

If you delete PFHDIR.HOL, then the next time you run PB you will 
be prompted to enter a number of days. For example, if you enter
1, then you will get the last 24 hours worth of directories.
