- This is the monthly FAQ list (Frequently Asked Questions list) for the
- newsgroup comp.os.msdos.programmer. Parts 2 through 4 of this article
- are posted as followups in the same thread. If the posting date shown
- above is more than six weeks in the past, see instructions in part 4 of
- this list for how to get an updated copy. (A separate article holds the
- changes from last month's edition. Look for the subject line
- "comp.os.msdos.programmer FAQ diffs".)
-
- FAQ lists are intended to reduce the noise level in their newsgroups
- that results from the repetition of the same questions, correct answers,
- wrong answers, corrections to the wrong answers, corrections to the
- corrections, debate, etc.
-
- This list should serve as a repository of the canonical "best" answers
- to the questions in it. The names of folks who have helped to improve
- this FAQ list follow the table of contents. If you know a better answer
- or even a slight change that improves an answer, please tell me! (Use
- email, please. Traffic in this group is high, and I may miss a relevant
- posted article.)

- Search tips
- ===========
- To search for specific topics: See the list of questions in the
- Contents section (immediately below) to find which article (part 2, 3,
- or 4) you need. Then, in that part, search for that question number.
- For example, while you're reading part 2 of this list, the trn
- newsreader command "gQ203" goes to Q203.
- To skip one topic and go to the next: Search for "Q" starting in
- column 1. In trn and similar newsreaders, the command "g^Q" does that.
- If your newsreader doesn't support searches, you can extract these
- articles to a file and use your favorite editor's search commands.
