/* File: main-vme.c */
/* Purpose: Support for "Vax Angband" */
/*
This is MAIN-VME C for VM/ESA machines.
First enable definition of VM in file "h-config.h"
You need to unpack archive EXT-VM VMARC .
To do that first set fixed file record length:
'COPYFILE EXT-VM VMARC A = = = ( REC F'
Then unpack:
VMARC UNPACK EXT-VM VMARC A
( if you don't have archivator vmarc, there is many places where you
get it, i got it from cc1.kuleuven.ac.be )
Then read MAKEFILE EXEC. It contains all neccessary information to
compile Angband.
EXT-VM VMARC content:
MAKEFILE EXEC
VMSERV TXTLIB
CNSHND ASSEMBLE
You will need about 3-4 MB free disk space to compile it.
If you have any problems, mail to
SM20616@vm.lanet.lv or SD30066@vm.lanet.lv
A large amount of this file appears to be a complete hack, but
what can you expect from a system designed for the Vax... :-)
