RestoreFile( filestateid,dorestore )
| RestoreFile | Restores a previously saved file state. |
| filestateid | A USHORT returned by the SaveFile method that identifies the file state to restore. |
| dorestore | An boolean integer constant, variable, EQUATE, or expression to indicate whether or not to perform the restoration. If omitted, the default of TRUE (1) is implied. |
The RestoreFile method restores the specified file state for the managed file. RestoreFile restores from states previously saved by the SaveFile method.
Implementation:
The RestoreFile method restores file position, as well as any active HOLD or WATCH. RestoreFile calls the RestoreBuffer method to restore the managed file's record buffer contents.
Example:
SaveState USHORT !must be a USHORT
CODE
SaveState = Access:MyFile.SaveFile() !save the file state
SET(MyKey,MyKey) !access the file (change the file state)
LOOP UNTIL Access:MyFile.Next()
!Check range limits here
!Process the record here
END
Access:MyFile.RestoreFile(SaveState) !restore the previously saved file state
