Note:

Table access can be optimized by using a separate command area for each table accessed by an application. Instead of having to search a TSR directory each time to determine where the table resides in memory, tableBASE uses a reserved field in the command area (table handle) pointing to the position of the table in the TSR. By keeping a separate command area for each table accessed, this table handle is used to quickly locate a previously opened table.
