Abstract: The 2.0.1 release of Tables included the ability to access table subsets. To the user and the programmer such a subset appears to have fewer rows and/or columns than the entire table. The user defines a subset by appending expressions to the table name. This is transparent to the programmer, as the program can just pass the table name to the usual table open routine. Internally, the procedure that evaluates the expressions calls two interpreters: one to evaluate the row selector expression, and another to evaluate the column selector. The syntax for the column selector follows usual Unix pattern matching, and the syntax of the row selector follows the syntax first used in qpoe filters.
