Access to tables in memory is accomplished using the table retrieval and update commands.
Indirect Table Access
This facility allows a table to be opened indirectly, by referencing a table name in another table, the primary table (see Figure 70). You can access a secondary table using an indirect open command for a primary table. Each secondary table name is associated with some other search criteria, which is then used to identify the desired table. In this way, time-sensitive or date-sensitive tables can go into production according to a specified time, date, or other criteria without operator intervention.
