+I backed out some of the changes, but it should compile and run on VMS.
+I removed the changes that guarantee that the scratch files get unique
+names; I did this because the resulting filenames would not work on
+some systems, and because if this is a problem I feel the correct
+solution would be to make sure each user is actually running in the
+correct unique directory, rather than changing the names of all of the
+temporary files that dvips might create. -tgr

+Subject: vms port and mods of hyper dvips 5.58

+
+I've picked up dvips version 5.58 from LANL, with Mark's hps
+modifications. I've ported (reported?) this to VMS. Below is a
+summary of my changes, followed by a copy of each changed
+routine (all changes are annotated with EJG).
+
+(It looks like whoever was keeping the vms port going hasn't
+worked on it for a while.)
+
+Thanks for the good work!

+
+This directory contains dvips 5.58 hacked by Mark Doyle to put in
+mods for hyperps and hacked by me to make sure it ports to VMS.
+
+This was obtained by following links from http://xxx.lanl.gov/hypertex
+in early July, 1996.
+
+Dvips has been made for vms v6.2 (alpha and vax) using DEC C
+v5.0.
+
+Main changes I made:
+
+******
+dvips.c
+
+include subdirectory [.vms] where vmscli.c is included.
+
+get process id and use in constructing file names
+dvips_h_pidxxxxx.tmp and dvips_b_pidxxxxx.tmp to replace head.tmp
+and body.tmp, so we don't get a name collision if two users are
+using the same scratch space. Change all references to these
+names to reference the variables holding the new names.
+
+******
+hps.c
+
+replace head.tmp and body.tmp as above.
+
+replace ERROR with ERROR_HPS to avoid collision with error()
+function. Question: why us a boolean variable to represent a
+constant?
+
+after the former head.tmp and body.tmp files are copied to the
+output, they are deleted. (neatness)
+
+
+******
+output.c
+
+replace head.tmp and body.tmp as above. Required a little bit of
+extra logic when testing to see if the output file is the former
+head.tmp (so we don't put in a \n). Don't want to do the test if
+the HPS_FLAG hasn't been set.
+
+******
+dvips.h
+
+include subdirectory [.vms] where vms.h is included.
+
+******
+[.vms]vmscli.c
+
+add qualifiers for new options since this file was last updated.
+
+fix up some bugs in qualifiers.
+
+******
+[.vms]dvips.cld
+
+add qualifiers for new options since this file was last updated.
+
+fix up some bugs in qualifiers.
+
+******
+[.vms]dvips.hlp
+
+add help for new qualifiers added above.
+
+make help agree with what the qualifiers actually do. For
+example, the /filter qualifier, sends the output to stdout, but
+still requires an input file (it will not read from stdin).
+
+******
+[.vms]newmake.com
+
+Made from [.vms]make.com. Don't prompt for options - all
+hardwired as defaults, except fontlib is turned off. HPS is
+defined in all cc's, and /standard=vaxc is added to all cc's.
+
+hps.c is included in the compile and link steps
+
+options file is removed from the link steps.
