How to categorize the typo err value apart from WHERE clause

[Sathish_jammy]

/*in the list of Cards - first one is exact word, followup are have typo err.*/

data CATEGORY;
input MODE :$20;
cards;			
A.VELOCITY
A.VALOSITY
A.VELOCIY
B.HYDROCHLORIC 
B.HYDRRACLORIK
B.HYDROCLOKIK
C.GEOMETRY
C.GEMENTRY
run;
/* the above dataset is just for an example */

/* I have a table in SQL with same kind of problem, As now just keep on eye with cards */ 

proc sql;
update CATEGORY
set Column2 = 'physics'
where MODE =* 'A.VELOCITY';
run;

proc sql;
update CATEGORY
set Column2 = 'chemistry'
where MODE =* 'B.HYDROCLORIC';
run;

proc sql;
update CATEGORY
set Column2 = 'maths'
where MODE =* 'C.GEOMENTRY';
run;

/*Is there any effective way to resolve this than some other methods in SAS */
/*I don't care about the initial (A. B. C.) but i need to focus on methods(velocity geometry hydrochloric)

MY MAJOR CONCERN ON CATEGORIZING "TYPO ERR"

You need to somehow standardize your data using some mechanism to group/cluster values with similar strings.

There are quite a few discussions and solution approaches around such "typo" problems in this forum.

To start with use search terms like: SPEDIS, COMPGED, FUZZY  ...and I'm sure the posts you find with these terms will give you ideas for other search terms you could use as well.
