.hl 1 Last Minute Notes
There are a few files on the distribution with filetype .LEO
which contain updated (later) command files.  They have not
been fully tested, however.
.s
Of special interest is a build file for RTEM, the RT11 emulator
that runs on VMS.
.s
Some last minute changes have been noted in CHANGE.TXT in this
account.  Some of these changes have been made, others haven't.
.s
One last-minute compiler bug has been fixed, but not adequately
tested.  The changed code affects only sequences such as:
.s.nf
	long	var;
	long	*laddr;
	long	func()
.s
	var _^= func();
	*laddr++ _^= func();
.s.f
Also, the following has been added after preparation of hard-copy
documentation:
.list
.le ;The setcc() function now runs on RSX-type systems.  It was
restricted to RSTS/E RT11 only.  (This has only been tested on
Vax-compatibility and RSTS/E).
.le ;Decus C runs on the PRO-350 with minor restrictions regarding
named directories.  We hope to submit a PRO native toolkit in
the near future.  Several routines have been added to the RSX
interface library for the PRO.
.le ;The archive program in the tools directory is augmented
by two simpler programs, archc and archx, which respectively
create and extract files from archives.
.s
While these have had minimal testing, their testing has included
Unix (4.2 BSD).  They were written to simplify file transfer
between "Dec-native" and Unix systems.

.hl 1 Getting Oriented
To build Decus C, first read NEW.DOC, KIT.DOC, all README.* files
and the command files needed to build Decus C on your operating system.
The command files will probably require editing before use on some operating
systems, especially RSTS/E and RT11.
.s
You should also read CC.DOC and WIZARD.DOC to learn about Decus C and
its run-time library.
.hl 1 Getting on the Air with Decus C
If you currently have a Decus C distribution, be sure you make a backup
of your current system, then initialize (zero) the accounts used for
the new system -- some files that were on the previous distribution have
been deleted from this one.
.s
There are a few incompatibilities which will require editing and recompiling
your C programs; the edited software will then be simpler to transport to other
C compilers and operating systems.  These are discussed in NEW.DOC, CC.DOC,
and the run-time library documentation.
.hl 1 Installation Time Estimates
Assuming all goes well, installation on RSTS/E will require about
one-half hour to create accounts and read the distribution tape and
about two hours to build all programs (using command file [5,1]RBUILD.CMD).
This assumes an unloaded 11/70 system.
.s
Installation on VMS will require about two and
one-half hours to read the distribution tape (because the tape is
written in FLX format and FLX will scan the entire tape for each
account).  Building all programs using command file [.COMMAND]VBUILD.COM
will require about two and one-half hours on a reasonably-loaded
VAX-11/780.
.s
Installation time on other systems should be comparable and, in general,
proportional to the disk access time.
