- This is the 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. Starting 2 Feb 1993, new and revised
- answers are marked with "new:" or "rev:" and the change date. The
- changes from the previous issue are posted in a separate article, with
- subject line "comp.os.msdos.programmer FAQ diffs".
-
- If the posting date shown above is more than four weeks in the past, see
- instructions in part 4 of this list for how to get an updated copy. (A
- separate article, posted before this one, holds the changes from the
- previous 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.) See the "From:" line in the header, or simply reply
- (rather than followup) to this article.

- Subject: Search tips
-
- This list is in digest format (if it's set up right).
- To skip one topic and go to the next: Search for "Subject" starting
- in column 1. In trn and similar newsreaders, the command "g^Subject",
- or a simple Ctrl-G, does that.
- To search for specific topics: See the list of questions in the
- Table of Contents (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 "g 203" (note the two spaces) goes to question 203.
- If your newsreader doesn't support searches, you can extract these
- articles to a file and use your favorite editor's search commands.
