on a VMS (aka OpenVMS) system

[.sys .os2] -- OS/2
[.sys .share .sounds] -- AIFF format audio files
[.sys .unix] -- guess :-)

The distributed copy of config.h will work successfully on VMS;
vmsconf.h has conditional code to deal with the UNIX-specific items.
-4. If you have the programming utilities lex or flex and yacc or bison,
- you may edit the procedure [.sys.vms]spec_lev.com and execute it to
- process several source files for NetHack's special level and dungeon
- compilers. If you use the version of these utilities from the OpenVMS
- freeware CD you will have to remove the include <stdlib.h> that yacc
- places at the top of each file. The provided spec_lev.com will default
- to copy pre-processed versions of the appropriate files (dgn_lex.c, lev_lex.c,
- dgn_yacc.c, lev_yacc.c, dgn_comp.h, and lev_comp.h) from [.sys.share]
- into [.util]*.c and [.include]*.h.
- If you choose to modify spec_lev.com, you want to run and test your
- changes prior to executing vmsbuild.com; otherwise, vmsbuild.com will
- do so for you and the results might not be what you expect.
+4. vmsbuild.com checks for several source files in [.util] and if it doesn't
+ find them, it uses [.sys.vms]spec_lev.com to generate them. If you have
+ the programming utilities lex or flex and yacc or bison, they be will
+ used if symbols are set up to run them. Or if you have them but do not
+ have symbols set up, you may edit spec_lev.com to have it run them.
+ If neither of those situations applies, spec_lev.com will default to
+ copying pre-genearated versions of the appropriate files (dgn_lex.c,
+ lev_lex.c, dgn_yacc.c, lev_yacc.c, dgn_comp.h, and lev_comp.h) from
+ [.sys.share] into [.util]*.c and [.include]*.h.
+
+ Once the file lev_yacc.c is in place, vmsbuild.com won't execute
+ spec_lev.com to make any of them, so if you decide to modify *_comp.l
+ and/or *_comp.y then you'll either need to execute spec_lev.com before
+ vmsbuild.com or remove [.util]lev_yacc.c so vmsbuild.com will do so.
+
+ If you use the versions of the lex and yacc utilities from the OpenVMS
+ freeware CD, you will need to pass "/Define=_DECC_V4_SOURCE" as the
+ third argument to vmsbuild.com in step #5. The version of yacc
+ or bison in that distribution places '#include <stdlib.h>' in the
+ generated code, before nethack's '#include "config.h"', leading to
+ conflicts that prevent compilation from completing.

advantage of them. If you do not already have a termcap file in use

be printed and NetHack will exit.

+ 'curses' interface, but the source code for it won't compile using
+ the implementation of curses which is supplied with VMS.
+
+6. NetHack contains code which attempts to make it secure in case it's
installed with privileges (to allow the playground to be protected
against world write access). This has only undergone limited testing,
so install NetHack with privileges at your own risk. If you discover
built NetHack, you can relink with tracebacks disabled by doing
$ @[.SYS.VMS]VMSBUILD "LINK" "" "" "/noTrace/noDebug"

don't have access to a privileged account yourself, then if you intend
to allow other users to access your copy of NetHack you should probably
place an ACL on the playground directory and its save subdirectory.

able to create files owned by them unless you have elevated privileges.

character when it wants input. This is displayed as ESC inside the
game. Digital VK201 keyboards (used by VT2xx and VT3xx and older
VAXstations) and VK401 keyboards (used by VT4xx, newer VAXstations,
be sure to remember to eventually reattach to the NetHack subprocess;
otherwise the game in progress won't get saved when you logout.
-8. NetHack optionally maintains a logfile which receives one line appended
+9. NetHack optionally maintains a logfile which receives one line appended
to it whenever a game ends. This can be disabled entirely by adding
an "#undef LOGFILE" directive to vmsconf.h prior to building the
program, or it can be disabled later by removing the file(s) LOGFILE.;*
from the playground directory. If not disabled prior to compilation,
the logfile can be reinitialized by simply creating an empty file
named LOGFILE in the playground, but make sure that users are able

+10. Some attempt at support for VMS versions earlier than V4.6 has been
included, but no such obsolete system was available for testing it.
vmsbuild.com detects the need for the extra support routines and
arranges automatically for them to be compiled. The reason that
underwent a major revision for VMS V4.6 and several routines which
NetHack utilizes were not available prior to that upgrade.

+11. vmsbuild.com collects almost all of the object files (xxx.OBJ) into
an object library (NETHACK.OLB) as it compiles the source files.
This should prevent the quota-exceeded problems from the linker
that some sites have reported for prior versions. Note that if you

will not be included in the new executable image.

spoil the game with unlimited wishes--you must be running from the
username compiled into the game via Local_WIZARD in vmsconf.h, and
you must specify "-D" on the command line when invoking NetHack.
$ @hackdir:nethack "-D"
Any character name you specify will be ignored in favor of "wizard".

+
+13. At program startup time, NetHack uses the empty file PERM to prevent
two different processes from using the same character name (under the
same UIC ownership) at the same time. It does this by temporarily
giving that file a second directory entry named PERM.LOCK, then
is accomplished using temporary entry RECORD.LOCK and LOGFILE using
entry LOGFILE.LOCK.

will not be able to use the X11 interface on VMS. Even if you do
have both those things, such a configuration has not been tested and
there are no provisions for it in vmsbuild.com. Makefile.src does
window manager in order for any changes to take effect; it's easiest
to just make the session manager quit and then log in again.

and the C compiler used.
