This directory contains the patches and the new ZOO 2.10 sources for VMS.

The supplied version incorporates some DECUS fixes to ZOO 2.1 for VMS
from August 1991 (concerning EOF handling, filename conventions, and
compatibility to VMS versions earlier than V 4.6.

The patch files are *.*_DIF; to apply the patches one must only run the
procedure DECUS_PATCH.COM. This procedure invokes the SUMSLIP editor
which is part of VMS. One will also find all new sources.


The full port to Open VMS (AXP) V 1.5 and DEC C V 1.3 was added at Monday,
27. September 1993 by Christian Spieler. This includes changes to remove
miscellanous warnings (mostly because of false include sequence of ZOO's
header files), and an adaptation of vmstime.c to the new (incompatible)
DEC C RMS header definitions. The supplied Make procedure VMSBUILD.COM
checks the architecture on which it is running  and uses the appropiate
compilation options.

The MSDOS port contains additional optimizations. It is possible to use
Assembler source for old fashioned compression (March 1992). There are
also new files, *.AI, and in [.MS-DOS] an updated MAKEFILE.TCC . Please
read MSDOS.TXT for further information.


Instead of VMSBUILD.COM, which needs all sources in the current directory,
one should use MAKE_DEC_C.COM. The files MAKE_DEC_C.COM and LINK_DEC_C.COM
are modified versions of the file MAKE_VAX_C.COM, which was provided by
Ralf Gaertner for the DECUS TeX 95 distribution in 1995.

This distribution has been checked sucessfully on VAX/OpenVMS 6.0 and
AXP/OpenVMS 6.1 with DEC C.
