Perform pattern matching using regular expressions.
Background Information
Regular expressions are a short and flexible way to match strings, so that you can locate particular characters, words, or patterns of characters.
The Caché ObjectScript pattern matching operator is also quite flexible, but does not provide the full range of syntax given by regular expressions. See Pattern Matching in Using Caché ObjectScript.
Available Tools
