Description
The RESTORE RECORDVIEW command restores a workarea status that was previously saved to the specified <memvar> with the SAVE RECORDVIEW command. RESTORE RECORDVIEW restores the following information:
- Workarea number
- Current record number
- Current index order
- Lock status
- eof() status
- bof() status
- found() status
The SAVE and RESTORE RECORDVIEW commands are useful in validation and hot key procedures when you want to move off the current record, execute a validation procedure, and then return to the same record. The SKIP 0 command must be used prior to a GOTO command in order to flush locked records to the disk if they have been modified.
Example
procedure check_value save recordview to m_recv // Validate data restore recordview from m_recv return
