- 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 EXTRACT, just type: EXTRACT 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 EXTRACT xxxxx assumes that the file to be searched is WORD.LST. Typ-
- ing extract 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: extract 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: extract qt~er xyz.lst or
- extract 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.
-
- This utility is also part of the WORDY package, by the same author. WORDY
- contains many more utilities.
-
- It is highly recommended that you obtain the WORDY package if you are
- seriously interested in generating word lists to study. The WORDY package
- contains the 100,000-word file WORD.LST containing nearly every valid word
- in use in competitive word games. It is obtainable from the author (see
- below). Note that the December 1995 issue (page 365) of PC COMPUTING maga-
- zine awarded WORDY a five-star rating (the highest).
