- Hello!
-
- The files on this disk are separated into several
- directories. The distribution disk has the following major
- objects:
-
- PDPROLOG.EQE - the non-public domain, proprietary PROLOG language
- interpreter. You may give PDPROLOG to anyone.
-
- If you purchased a Prolog system from us, another disk contains
- a copyrighted A.D.A. Prolog system.
-
- <SAMPLES> - This disk directory contains a variety of Prolog
- programming examples which illustrate some of the points of
- Prolog programming. Note that the book mentioned above
- unfortunately contains numerous mistakes in the examples. You
- should refer to these files for the corrections.
-
- <EXPERT> - This directory contains Simon Blackwell's public
- domain expert system shell program. The documentation is not
- complete yet.
-
- <ATN> - This directory contains Lou Schumacher's natural
- language parser. The initials "ATN" stand for augmented
- transition network.
-
- USQ.EXE - This program is the key to accessing the files on the
- disk. Read the below explanation.
-
-
- The files on this disk are supplied in squeezed format. You
- can always tell a squeezed file because the part of the name
- after the period has a "Q" as the second letter. For example,
- the file "prolog.eqe" is the squeezed form of the file
- "prolog.exe".
-
- You can't execute or read a file that is squeezed unless you
- unsqueeze it. This is done with the program "usq.exe" which is
- supplied on this disk. Don't do this on the distribution disk -
- there isn't enough room to hold the unsqueezed file. And make a
- copy of the distribution disk and put the original safely away.
-
- For example, to unsqueeze "prolog.exe", put the file
- "prolog.eqe" on a disk or directory with sufficient space to hold
- the unsqueezed file, put "usq.exe" on the same disk or some
- other, and run usq, as in: "A>usq prolog.eqe (carriage return)".
- The usq program will automatically generate "prolog.exe" with the
- proper name, since that information is stored in the squeezed
- file. Next erase "prolog.eqe", since it takes up space and is no
- longer needed.
-
- If you have a floppy based system, it is best to transfer afew
- files at a time and unsqueeze them. The "usq" program
- accepts wild card commands, which means that you can say "usq
- b:*.pqo", or "usq *.eqe". If you have a hard disk based
- system, you have another option. Simply copy the entire contents
- of one of the directories of the distribution disk into an empty
- directory on your hard disk. In fact, you can copy everything
- from the distribution disk into a directory and give the command:
-
-
-
-
-
-
- "B>usq *.* (carriage return)".
-
- To completely understand the options of the usq program, note
- that running it without any command line arguments produces a
- table of options. The command is: "usq (carriage return)"
-
- Finally, if you have a problem, don't stare at it in morose
- frustration. Give me a call!
