January, 1995
It would be convenient to have the computer find in the master word list all
words containing any given set of letters. The letters might be in any random
order in the words selected, but they would all be present in that word. This
would be useful for creating lists of words with unusual letter combinations
for study to increase one's skill at Scrabble (tm) and similar word games.
Likewise, certain letters can be excluded from the words to be found. This
makes it possible to, for example, find all "valid" words containing q and t,
but not r and e.
To use XTRACT, just type: XTRACT xxxxxx yyyy.yyy, where xxxxxx stands for
letter set that you wish the word list to be searched for, and yyyy.yyy is
the name of the file you want to have searched. All "valid" words containing
all letters in that set, in any particular order, will be extracted and saved
n a file with an .xtr suffix.
Typing XTRACT xxxxx assumes that the file to be searched is WORD.LST. Typ-
ing xtract abcd searches the file word.lst for the letter set abcd.
To exclude a certain letter or letters, precede the excluded letters with an
~ or with an !, those being the standard symbols for logical NOT.
As an example, to find all "valid" words containing the letters -zf- in the
file word.txt, simply type: xtract zf word.txt. After a few seconds wait,
the file zf.xtr will contain all words containing that unusual combination
contained in the file word.txt.
As a second example, find all "valid" words containing the letters -qt-, but
excluding -er- in the file xyz.lst. Just type: xtract qt~er xyz.lst or
xtract qt!er xyz.lst. Either method works fine.
Note that it is possible to specify only letters to exclude, for example, by
typing ~aeiou or !aeiou, obtain a list of all words not containing any of the
letters a, e, i, or u, but any other letters.
The entire WORDY package still costs only $2.00 (cheap!) to register - a real
value in these days of inflated shareware registration fees, not to mention
overpriced commercial software produced by committees of overpaid profession-
al programmers.
