Hi Friends,
actually I can't able to understand the question.
please repeat again in a understandable way.
scan: it returns Nth word from character observation.
index: it return starting position of the character from
character observation.
index C: it returns starting position of any character from
character observation.

The questions is to locate and not to extract any
particular word from a string of 150 bytes. SO, according
to me INDEX is the best.

Answer / jothi sankar
INDEX is best one. Is for getting location of mentioned
data.
Eg:
str1 = 'Hi i am fine here. how are u there ? .....';
str2 = index(str1,'how'); --> str2 = 20
SCAN is to get a substring upto mentioned character
INDEXC to locate only for mentioned one or more single
character

Answer / yaga
I think Index is the best option to locate the word
beacause SCAN is SAS function to extract the particular
word positioned in nth place. for ex: 2 word from the string
