What's new? Is this group dead, or is something happening (#14)

Neither the group nor the goal of the group is dead, although
it might be charactarised as sluggish.

The most recent new addition is QuickForward, a whole new
project directly related to the underlying goal of the
group. (Information is included under

What is this newsgroup all about? (#1)

The newsgroup was created for discussions about the project to
create a free but completely compatible alternative to
MicroSoft QuickBasic. However, discussions about the use of
this compiler (once it is functional) are on topic. Discussions
about any free BASIC compiler can be considered on topic, as
well, particularly if the source code is available (GNU
definition of "free"). Discusions of compiler creation in
general are on-topic insofar as they relate to any on-topic
project.

Discussions about programming in BASIC are not on topic here
and should be directed to another newsgroup (such as
alt.lang.basic) instead unless they pertain to writing a
compiler or interpreter specifically or something related to
that task (such as a program designed to test a comnpiler).

Why aren't there very many posts? (#13)

Several reasons. For one thing, the initial excited discussion
has died down, and since everyone working on this is doing it
in his Copious Free Time, progress is slow.

Also, it's an alt group, and many news admins feel that it's a
small and unimportant one at that, so it has a tendency to have
short expiration times.

Actually, there are advantages to being a low-bandwidth
group. If it were a high-bandwidth group, there are times when
I would feel pressure to quit reading it faithfully in order to
get other things done in my life. As it is, I'm never tempted
to quit reading albc.

Help! My news server doesn't carry this group! (#10)

Not every server carries the group. Fortunately, there are free
services that do carry it. The following are known:

http://www.freeserve.net/
http://groups.google.com/groups?hl=en&safe=off&group=alt.lang.basic.compiler
RemarQ

I'm told that freeserve offers a regular news server,
news.freeserve.net, although I think you have to be a member to
use it. Their service appears to be free but only available in
the UK.

There is also a list of public news servers at
http://www.newzbot.com/ which may be helpful, as some of them
may carry albc.

How did this project get started? (#2)

In the summer of 1998, jdm posted the original "Feeler"
message:

    Subject:  Feeler - Free QB replacement clone project
    Groups:   alt.lang.basic, microsoft.public.basic.dos

    Body:     How many of you would be interested in a joint
              development project to develop a replacement
              for Quick Basic, in somewhat the same spirit
              as FreeBSD or the GNU software foundation?

              This would be a direct replacement for Quick
              Basic 4.5, as close as we can legally get
              without infringing on any copyrights.  The ideal
              would be to have the capability of compiling
              any Microsoft-dialect Basic code to a similar
              sized .EXE as Quick Basic.

              The rationale for this proposal is twofold:

              First, the supplies of Quick Basic are drying
              up.  Used software vendors want premium
              prices for it.  There is a steady demand for
              something that can compile QBasic code on
              these newsgroups.

              Second, other compilers that are available
              for DOS - based Basic programming are
              not compatible with Microsoft dialects.  The
              most notable - Power Basic - is a descendant
              of the old Borland Turbo Basic and is not
              even close to the same dialect as QBasic.

              I'm not a compiler person, so I'd defer that part
              of it to someone with extensive compiler
              experience, but I've almost 18 years experience
              now in developing business applications in
              several different languages/IDE's.  I'm good with
              UI stuff, editors, file management, printing, that
              sort of thing.

              Let's have a discussion about it.  Everythings'
              open at this point, i.e. what language we'd use
              to develop it, how many features to put into the
              initial version, who'll do what, etc.


              --
              jdm

This post received a lot of responses (just search Google
Groups for "Feeler - Free QB" and you will find them), and
discussion followed. Once we had enough support, Ali Afshar
posted a proposal in alt.config, and after some discussion
there this newsgroup was created.

How far along is the project? (#3)

We have proceeded from discussion to initial coding, passed
through an internal argument, and split into more than one
group working separately in more than one language. At least
two additional related projects have since been
declared. Specifically, one IDE has been released in alpha
form, written in C. There is a project underway to code a
compiler in QBasic itself, and a separate project to create a
QBasic-to-XBasic translator (in XBasic) and glue it onto the
frontend of XBasic, and another compiler done in PDS7 (called
QuickForward). None of these is finished yet, however.

Can I Help? (#8)

Yes. You can help. The first thing to do is to subscribe to the
newsgroup and read the other online resources (See the answer
to #6). Then figure out which related project you can
contribute to. Then you'll be ready to pitch in!

What is available on the internet related to this project? (#6)

To have your resource added to this list, email the maintainer
with a short description of the resource and the URL where it
can be found. These should be related to on-topic projects (See
"What is this newsgroup about"), not URLs for other
BASIC-related websites.

Who is in charge? (#4)

The guy who writes a portion of code is in charge of that
portion of code, essentially. So, write some code; then you'll
be in charge of something! Various people are "in charge" of
various subprojects by virtue of having started them. Some code
is also governed by virtue of the license it uses (e.g., GPL).

What language is it to be implemented in? (#11)

Several different languages. One group is working on
implementing it in QBasic, another in C++, another in PDS, and
another in XBasic. I actually thought breifly about starting a
separate parser in elisp...

What is to be the target language/platform? (#12)

The idea is to design it in a sufficiently platform-independent
way that everyone can use it. That said, DOS is near and dear
to the hearts of many QBasic users, and should be considered a
valuable target platform (although Windows is more common these
days). Hopes are to have versions for other platforms as
well. Code generation is, of course, target-specific, but we
hope to design it in such a way that modules can be written for
different targets and plugged into the same parser. We'd also
like to see ANSI-C output as an option... Of course, the
wishlist is long enough to take us until 2147 to finish
implementing, but nevermind that.

What do the version and serial numbers of the FAQ mean? (#5)

The serial number is just the date, in the form YYYYMMDD. Early
versions (0.0.nn) were YYMMDD, in which case you can assume
that the first two digits of the year were "19".

The version number is in the form V.v.n greek letter.

The first number, V is the major version number. I tenatively
propose that it should change whenever the FAQ is handed off to
a new maintainer.

The second number, v, is the minor version number, and jumping
to a new v represents a reworked version.

The third number, n, is the release number, and changes with
every release, generally.

In principal any of these numbers can have any number of
digits, but n is the most likey to have multiple digits, which
is why I started it at two.

The greek letter is independent of the rest of the version
number (which means that if there is a 0.0.01 alpha there will
not be a 0.0.01 beta) and indicates the target audience. Alphas
are meant for those interested in developing only. Betas are
meant for those interested in developing as well as those
interested in testing. Gammas (and the letter gamma may be
ommitted altogether, and should be understood if there is no
letter) are meant for everyone, including end users. I do not
expect any gamma FAQs to appear until the compiler can handle
most QBasic code at least. Anyone may read any FAQ version, of
course, but alpha FAQs are probably not productive or
worthwhile for end users to read.

Incidentally, old versions of the FAQ are available from the
maintainer, should anyone want them at some future point in
time for some as-yet-unforseeable reason. I'm a packrat, and I
keep everything.

This version is old -- where do I find an update? (#9)

You can always get the latest version of the FAQ from the
maintainer. Send an email to jonadab@bright.net. Put the
abbreviation albc (stands for alt.lang.basic.compiler) in the
subject line, and ask for the latest FAQ. Specify HTML or plain
text, and specify whether you'd like it as an attachment or in
the body of the message. The latest version of the FAQ is also
now available in HTML form on the web at
http://www.bright.net/~jonadab/albc/. The version in plain-text
form available from the rtfm.mit.edu archives may lag as much
as a month behind. (At the rate I've been updating the FAQ
recently, that's not a really big issue.)

Revision History

Version 0.2.04 alpha. Serial number 20010904.

   o Added perhaps the most frequently asked question of all,
     What's new?
   o Added information about QuickForward
   o Added terseness to introduction.
   o Made minor technical improvements to the underlying markup
     of the HTML version, in partial preparation for eventually
     moving to XHTML.
   o Replaced references to Deja with Google.
   o Rephrased the question, What is available on the internet
     and updated the answer to include QuickForward.

   o Updated answer to What is the target platform
   o Removed dead link from a link tag in the header of the
     HTML version.
   o Replaced quotation marks with proper HTML entities in HTML
     version. This markup change was long overdue.
   o Removed some obsolete HTML comments that never showed up
     in the text version anyway.
   o Some cosmetic changes to the HTML version as a side-effect
     of having updated the elisp code I use to maintain web
     pages.

Version 0.2.03 alpha. Serial number 19991213.

   o Cosmetic changes. For example, the HTML version now uses
     cascading style sheets.
   o Updated What is this newsgroup all about? to explicitely
     list general discussion about programming in BASIC as
     off-topic and suggest a different newsgroup.
   o Fixed a bug in My news server doesn't carry this group
     which caused the url for the list of public news servers
     to fail to appear in plaintext versions.
   o Updated How far along is the project?
   o Added terseness to Can I help?.
   o Removed dead links from What is available on the internet?
   o Added terseness to Who is in charge?.
   o Adjusted information about XBasic in What language is it
     to be implemented in?

   o Removed dead links to #7, which was removed in 0.2.02.

Version 0.2.02 alpha. Serial number 19990703.

   o Who is involved (#7) was removed, being very much
     obsolete. What resource are available on the internet was
     given much-needed updates. What language is it to be
     implemented in was updated, having become obsolete.
   o Various other updates and some cosmetic changes.
   o The document was made available on the web again, in HTML
     form.
   o First posts to news.answers were of this version.

Version 0.2.01 alpha. Serial number 19990526.

   o Added DejaNews Classic and also RemarQ under My news
     server doesn't carry this group

Version 0.2.00 alpha. Serial number 19990420.

   o Earlier FAQs were maintained in 7-bit ASCII to allow for
     posting to usenet; as of this version I HTMLised the whole
     thing and use an automated converter to derive the 7-bit
     ASCII version for posting.
   o Removed the reference to the defunct U.S. mirror of the
     website.
   o Removed the reference to the defunct volunteers list.
   o Added the real URL that the come.to address points to.

     an update?" (#9)

Version 0.1.00 alpha. Serial number 19990122.

   o Reworked several questions to better reflect current
     status and generally be more up-to-date.
   o Adjusted #7 and a couple of others in light of the
     information on the web site.
   o Gave numbers to the remaining unnumbered questions (#11
     and #12, now) and answered them a bit better.
   o Added "Why aren't there very many posts?" (#13)
   o Initiated 4-digit year in serial number. (I know, nobody's
     ever going to do a computerised search or sort of these by
     date, but I did it anyway. It's only two more bytes.)
   o Minor adjustments elsewhere that I already forget
     about. The old versions are still available if anyone
     cares.
