[VAX83D.SFBRAUN.DTRPAT]AAAREADME.TXT

Someday, perhaps, the DTR32 people will realize that, whatever n/0 is,
it isn't negative one.  This directory contains a patch to DTRSHRxx.EXE
(the DataTrieve-32 V2.0 shared image) that forces divide by zero to
be a zero result, with no error message.

To use this, modify your DTRBLDxx.COM file in DTR$LIBRARY to include
the DTRSHRPAT.OBJ object module.  This provides a patch area for PATCH
to work in.  You also need to modify the link step for DTRSHRxx.EXE
to make the symbols "DTR$$EAR_DIVIDE", "DTR$$EAR_ADD" and "DTR$PATCH"
UNIVERSAL (the patch file needs these definitions).  Then, rebuild the
DTR images with "@DTR$LIBRARY:DTRBLDxx".

Finally, apply the patch file.  You should modify the image name in the
first line of DTRSHRF2.PAT for the particular image you are patching.
The given file DTRSHRF2.PAT is for DTRSHRF2.EXE.  You may be using
different suffix(es).  To apply the patch file, simply use:
"$PATCH @DTRDIV0F2.PAT".
