Operating instructions for MFIND
MFIND is a utility program specifically designed for
doing simple name searches on the movie database. Here are
some examples of its use:
A>mfind
Search request #0 (e.g. Winger and Nolte) (Null line to stop):
Lou Gossett Jr
- lists all movies with Lou Gossett, Jr. in the cast
Search request #1 (e.g. Winger and Nolte) (Null line to stop):
Gossett
- same as above
Search request #2 (e.g. Winger and Nolte) (Null line to stop):
Winger and Nolte
- finds the movie starring (Debra) Winger and (Nick) Nolte
Search request #3 (e.g. Winger and Nolte) (Null line to stop):
MacLaine or Maclaine
- useful when not sure of spelling; the same effect could be
obtained by using MacLaine in one search set and Maclaine
in the next.
Search request #4 (e.g. Winger and Nolte) (Null line to stop):
Pink Panther
- finds all movies with Pink Panther in the title
Search request #5 (e.g. Wigner and Nolte) (Null line to stop):
(Aust.)
- finds all Australian movies
Note that each search statement (i.e. each line of search criteria)
is independent of other lines. Each movie entry that matches
a particular search statement will be saved in memory.
After the entire database has been examined, you will have the
opportunity to separately review all of the movies that have
matched each search statement.
Up to 15 search statements may be entered.
Additional Notes:
This program is fairly simple-minded. If the second term in a
search statement is AND or OR, then the first and third terms
are used as search arguments. If AND/OR is not found, then
the entire string is used as a search argument. In other words:
ILLEGAL: Debra Winger and Nick Nolte
LEGAL: Keaton and Allen
to find all Diane Keaton and Woody Allen movies.
(Also finds all Diane Keaton and Karen Allen movies.
Note: if any movie had the name "Allen" in the title
it would also be found")
There is no "wild card" capability.
ILLEGAL: D:xxLester
LEGAL: D:Richard Lester
or
Richard Lester
or
Lester
(though this last one will probably show more movies than
what you had in mind)
Installation Instructions
Installation of this package consists basically of copying all files
into a subdirectory on your hard disk.
If you do not have a hard disk, then you will need to do some additional
setup work. Because MFIND only knows about the currently logged-in
directory, it won't find files that are on another disk drive. You can
get around this problem in several ways:
1 - In later versions of DOS, you can use the JOIN command to connect two
directories into 1 logical directory. See your DOS manual.
2 - You can copy everything into a RAMdisk, such as created by the IBM VDISK
program or any of the other RAMdisk problems available.
3 - You can run MFIND separately against each diskette.
Principles of Operation
The program starts with the first entry in the current disk directory.
For each filename that consists of two-letters, the file is opened and
searched. As each movie record is processed, the information for each
movie is built into a single field for search purposes. Matches are then
done on character strings within this entire field. When a match is found,
the entire entry for the movie is displayed on the screen. As each file is
searched, the name of the file will also be displayed. There is a limit of
200 hits for any one search statement and about 500 hits for all search
statements. A typical search will take about 2 minutes on an XT.
Note: This program will operate with any free-form text files whose records
are separated by two dots (..), with no record larger than 1000 bytes, whose
filenames consist of 2 letters, and where no file is larger than 24K bytes.
