Answer / rajat singh
In a regex lookup operation, each record in the lookup file must contain a regular expression in the format described in “Regular expressions in DML functions”. The regex key specifier of a regex lookup file identifies the record field to interpret as a regular expression.
A lookup function such as lookup (file_label , expression) tests the value of its second argument against the regular expression field in each record of the lookup file, until the function finds a match.

will be defining values like 0|1|2|3
