Tables, flow charts, and program logic

There are, of course, many problems meriting further investigation: tables in their present form can become unwieldy when problem segments are prefaced by one or two simple decisions rather than six or seven complicated ones; it would sometimes be convenient to have rules in a table refer to other rules in the same table; rule identifiers in which the variable values are connected by (“or” rather than (“and” would sometimes be a convenience, and so on. Such further investigation would be desirable, since it would enhance the already considerable merit of tables as a means to implement program logic.
