How to tell if one string variable contains another string?

The “index” function can tell us whether one string variable contains a fixed string, but what if the string I am searching for is varying among different observations? For example: there are two variables: v1 and v2. V1 is a short string and v2 is a long string. V1 can be “sgd” and “kjh” And v2 can be “hdsgdk” and “ukjhso”.

Which is a string V1 or V2?

V1 is a short string and v2 is a long string. V1 can be “sgd” and “kjh” And v2 can be “hdsgdk” and “ukjhso”. Obviously v2 contains v1 for these two cases. Any SAS functions can help me with this?
