the ftp site is liege.ics.uci.edu (internet address 128.195.1.5)
detailed info from Arcadia is attached below.

also, if you are using Meridian's compiler you will probably
trip across a compiler bug in each of aflex and ayacc. They are relatively
trivial to workaround - and Meridian has been notified.
I have patches but havent sent them to Arcadia yet,
if anyone needs them, send me mail & I'll forward them.
The patches to work around other compiler's bugs are generally included.
(wont it be nice when thats not an issue :)

and for those who want to really push aflex.
second - aflex in particular is a little hard to customize without
editing the generated output.  I have a version that makes it easier
to customize, reads 8K blocks using POSIX_IO instead of one char at a time
using Text_IO, preserves form feeds in the input stream and is alittle faster.
I havent submitted it anywhere public yet because I want to make a few more
improvements first, but ifyou or anyone else wants it, just ask.

**********************************************************************

This is the IRUS (Irvine Research Unit in Software) aflex/ayacc public
distribution.  Aflex and ayacc are similar to the Unix tools lex and
yacc, but they are written in Ada and generate Ada output.  They were
developed by the Arcadia Project at the University of California,
Irvine.  Aflex is based on the tool 'flex' written by Vern Paxson.
These tools are copyrighted, but are freely redistributable.  There is
no warranty of any kind (see the copyright notice above.)  However we
do ask that you report any problems you encounter as we use these
tools ourselves and we want to fix any bugs that are found.

You may give this software to others, but we prefer that those who can
get it directly from us to insure that all users are running the
latest version.  We also ask that you send electronic mail to the
address [e-mail] giving your name, your
organization, a paper mail address, and your e-mail address (either an
Internet address or a UUCP path relative to a well-known site such as
uunet.)  A form is provided below for your convenience.  We will use
this information to set up a mailing list to announce new versions of
aflex and ayacc, as well as new software that is expected to be made
available.

The distribution is currently available on the machine
liege.ics.uci.edu in ~ftp/pub/irus/aflex-ayacc_1.1.tar.Z.  Full
instructions for retrieving and unpacking are enclosed below.  If you
have trouble retrieving or unpacking the distribution send mail to
[e-mail] (or via UUCP to
uunet!sdcsvax!ucivax!irus-software-request) If you have trouble with
the tools information on how to report bugs is present within their
directories.

How to obtain aflex and ayacc via anonymous FTP

1.  FTP to the machine liege.ics.uci.edu (internet address 128.195.1.5)

2.  When asked for a username use 'anonymous'

3.  When asked for a password use your username on your local machine.

4.  Change directory (cd) into the pub/irus directory.

5.  Set a file transfer mode that will allow you to transfer binary
    files.  One way to do this that usually works is to issue the
    command 'type tenex'

6.  Type the command 'get aflex-ayacc_1.1.tar.Z'

7.  Quit FTP.

8.  You now have a compressed tar file containing the source for aflex.

9.  You need to uncompress the file by typing
    'uncompress aflex-ayacc_1.1.tar.Z'

10. Now untar the file to create the source and documentation tree by
    typing 'tar xvf aflex-ayacc_1.1.tar' at the Unix prompt.

11. Read the README files in the aflex/README and ayacc/src/READ_ME to
    find out how to compile the tools.  If you are using the Verdix Ada
    Developemnt System Version 6 be sure to read the VADS6.README files
    in the aflex and ayacc directories before building them.
