the question is as following, I could not find a good answer:
in a text file or a database, there are some lines of string, such as
abcde
bcdef
cdefg

then another string are given picked from it but with a random order, such as "cbdea", from this given string, how could I pick out the relative one(should be "abcde") from the text file or the database?

thanks in advance

The following script assumes that no letters repeat themselves.




#VAR randomstring %1  // or however you want to define it.


#VAR foundIt 0


#FILE 1 relatives.txt


#VAR record 0


#UNTIL @foundIt {


   #ADD record 1


   #VAR testword %read(1, @record)


   #VAR goodLetterCnt 0


   #LOOP %len(@randomstring) {


      #IF %pos(%copy(@randomstring, %i, 1), @testword) {#ADD goodLetterCnt 1}


      }


   #IF (@goodLetterCnt = %len(@randomstring)) {#VAR foundit 1}


   }


#SAY The relative of @randomstring is @testword~.


#CLOSE 1

Basically, it pulls a test word from the file, then checks to see if each letter of the random string is in the test word. If so, it reports, if not, it moves on to the next test word.
