Writing Transactions From the Buffer

When users make changes to the database (using the CHA, INP or DEL commands), HLI stores these changes in buffer or a shadow page until one of the following happens:

• The buffer becomes full.
• A program finishes execution.
• A program closes down a FOCUS file when CLO is issued.
• A program issues a SAV command.

When any of these events occurs, all pending changes for all programs are written to the database (even if someone else's program issued the CLO or SAV command).
