Description

The SAVE DATASESSION command is used to save the status of all open database tables. The SAVE DATASESSION command saves the following information pertaining to the current session for each open table:

• Currently selected workarea
• Workarea number
• database name
• full path of table
• all index files
• Current record number
• Current index order
• Lock status
• eof() status
• bof() status
