Description
The RESTORE DATASESSION command is used to restore the status of all open tables. The RESTORE DATASESSION command restores the following context pertaining to the saved session (See SAVE DATASESSION):
- 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
- bof() status
- found() status
The SAVE DATASESSION command may be used to save 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
