Description
The SAVE RECORDVIEW TO command is used to save the status of the active workarea to the specified memory variable <memvar>. The SAVE RECORDVIEW command saves the following information pertaining to the active workarea:
- Workarea number
- Current record number
- Current index order
- Lock status
- eof() status
- bof() status
- found() status
The RESTORE RECORDVIEW command may be used to restore the above information from the specified memory variable. The SAVE and RESTORE RECORDVIEW commands are particularly useful in validation and hot key procedures when you want to move off and then back on the current record. The SKIP 0 command must be used prior to a GOTO command in order to flush locked records to disk if they have been modified. SET CLIPPER must be ON for SKIP 0 to work correctly.
