Table B (File architecture)
This topic covers the internal architecture of a Model 204 Table B page.
For a discussion of the ways a File Manager may organize these pages in a file, please refer to File Design (File Management).
At a minimum, Table B contains all of the base records in a Model 204 file. If Table X is not enabled it also contains all extension records. If Table E is not enabled, then any data whose contents is greater than 255 bytes must be held as a series of repeating fields.
