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 cursor/workarea
• Cursor/Workarea number
• Database name
• Full path of table
• All index files
• Current record number
• Current index order
• Lock status
• eof() status

The RESTORE DATASESSION command may be used to restore the above information. SAVE and RESTORE DATASESSION can be used with Recital Web session variables ( _SESSION[ ] ) to maintain context between different .rsp web page requests.

_session[ "statevar" ] = statevar
 
// you can then restore the session on the next web page request like this
