Archive-Name: rot13/part01
Hello.
This is a dual posting of a rot13 program and a unix chat program. I felt
bored, so I took some existing source both ways and modified it. The rot13
program was originally by Scott Berry, and only ran under VMS. It only
had the C source file. It now has a Makefile for UNIX, a Config.MMS file for
VMS, and a .CLD file for VMS. It's only in beta at this point. I've still
got to finish the part of the program that handles the .CLD.
The Chat program was originally from Citadel/UX, and intended for a BBS
environment. While not the best chat in the world, it is simple and easy
to maintain. If you are the chat maintainer, you MUST be the first one
to run it after you delete the chat.tmp file every so often. The chat.tmp
file that's created serves two purposes:
1) to log the chat
2) to provide history capability

X1.12j Rot13 01-28-91
X
XNote: Although this is version 1.12j, it's still in beta test. I've still
Xgot a few things to do to it, but when I finish it, I'll release it in a
Xset of programs.

X
XWhat is Rot13?
X
X Rot13 is a program to convert text files into rot13 format for
Xusenet. This is often useful when you think you have some text that might
Xbe offensive to some people.
X
XHow do I run Rot13?
X
X Just use the syntax:
X
X rot13 <infile> <outfile>
X
XWhere <infile> is the file to be processed, and <outfile> is the file to
Xbe written to.
X
XWhat systems support Rot13?
X
X I have sucessfully compiled it on an IBM RT running BSD 4.3, a
XSPARCstation running GNU, and some HP-9000's running GNU, as well as a
XVAX 6440 running VMS 5.3-1.
X
XHow do I build Rot13?
X
X Under UNIX, just type 'make'. Under VMS, just type 'MMS' at the DCL
Xprompt. It will automatically build itself.
X
XWhat about the compile time errors that my compiler _may_ give me?
X
X You may have an error that looks like this:
X
Xmain: Function has no return statement.
X
XI'd appreciate help on eliminating this so I can completely clean out the
Xsource.
X
XNOTE ABOUT rot13.cld:
X
X It's not quite finished yet. I still have to finish that section.
XFor now, under VMS, install ROT13 with a line in your login.com (or
Xsylogin.com) that looks like:
X
X$ ROT13 :== <disk>:[DIR...]ROT13.EXE
X
XPretty soon, you'll only have to edit the .CLD file to point to the location
Xof the executable and have a line in your login.com that resembles:
X
X$ SET COMMAND ROT13.CLD
X
XUsing CLDs is a much faster and efficient way to install it.
X
XPlease send bug fixes, etc to me in the form of context diffs.
