find words inside string : words inside array

[AlexeyS]

Hello, i try to know if specific words are within text. i use function findw.

the problem is that i defined words inside array and when i run the function findw(text,word(i)) i didn't get answer, but when i write specific words by myself, i get right answer. for example findw(text,'sea').

data for example is :

          text                       word1    word2    word3

the car is beautiful           best        car         

blue sea                           sea        blue        exist

i saw that length,format and informat of array word is length 8, maybe this is problem? Whta i should do?

my program look like :

data test;

set text;

array word (3) $ word1-word3;

array exist_ind (3);

do i=1 to 3;

    ind(i)=findw(text,word(i));

end;

run;

You are right: the search is unsuccessful, because in the array "word" the strings are padded with blanks.
You can add the 'r' modifier in the findw function to remove leading and trailing blanks(delimiters):

data text;
infile datalines missover;
input text $20. (word1 word2 word3) (:$8.);
datalines;
the car is beautiful best car
blue sea sea blue exist
;
run;
data test;
set text;
array word (3) $ word1-word3;
array ind (3);
do i=1 to 3;
ind(i)=findw(text,word(i),' ' ,'r' );
end;
run;

Hello,

use the strip function to eliminate blanks from word{*} variables.

data want;
set have;
array word (3) $ word1-word3;
array exist_ind (3);

do i=1 to 3;

    exist_ind(i)=findw(text,strip(word(i)));
put _all_;
end;

run;
