The LIKE operator supports rudimentary pattern-matching. CONTAINS (or ?)
checks for a substring on the LHS that matches exactly a sting on the RHS.
The INDEX() function searches for the postion of the first character in a
character string of a substring that matches the second argument of the
function. (In the future SAS will also offer a fuzzy index function.)

hello.

solaris, SAS v 8.2.

appart from being able to use index in a where and subsetting if, what
is the difference between using these operators or function?
