I'm not sure I understand what you try to accomplish here.If you know what words (or extracts) to search for you can start looking at the FIND function.
Maybe you can give us some more examples and expected result.

If you are refering to characters, not words simply do:
data _null_;
x = 'Environmental Studies' ;
y = substr(x, length(x) -4, 3);
put y;
run;

You stated 10 - 15, but your example showed 3 of the last 5.

this code takes a character string of words and just gets the last 3 words. I purposely made the length of the words different. Don't know if this is the kind of thing you wanted to do.

data temp;
wordstring = 'abc defg hijkl m nop qrstuvw xyz';
end1 = length(wordstring);
array start{*} start1-start3;
array end{*} end1-end3;
array lngth{*} lngth1-lngth3;
start1 = anyspace(wordstring,-end1) + 1;
lngth1 = end1 - start1 + 1;
word1 = substr(wordstring,start1,lngth1);
do i = 2 to 3;
start{i} = anyspace(wordstring,-(start{i-1}-2)) + 1;
lngth{i} = start{i-1} - start{i} -1;
end;
word2 = substr(wordstring,start2,lngth2);
word3 = substr(wordstring,start3,lngth3);
run;
proc print data = temp;
var wordstring word1-word3; run;
