KSH 88 help requested

[Larry W. Virden]

I am looking for patches and doc for ksh88.  When we were sent our copy
from the ATT toolchest, we apparently didnt receive the unformatted
doc that we had requested.  Now we are trying to track it down.
Also, we have been told in private email messages hat there have
been a number of 'minor fixes' made to the initial version of ksh88 from
folks who SHOULD know.  But when we try to talk to the Toolchest about
getting an update, we are told that the original version available
is the only version and that there are no updates available.  But
we are getting some core dumps in at least two places (on a Sun SPARC
and one place on a 
Sun 386i) and would like to find the fixes for these.  Are there
any patches available on the net?
