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
- Current record number
- Current index tag order
- Lock status
- eof() status
- bof() status
- found() 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.
Example
save datasession close all // open up some new tables in a new datasession restore datasession
save datasession to statevar _session[ "statevar" ] = statevar // you can then restore the session on the next web page request like this statevar = _session[ "statevar" ] restore datasession from statevar
