Open( cascading ), VIRTUAL, PROC
| Open | Opens this object's primary file (see Me) and any related files as directed. |
| Cascading | A numeric constant, variable, EQUATE, or expression that indicates whether this method was called by itself (recursive). A value of zero (0) indicates a non-recursive call; value of one (1) indicates a recursive call. This allows the method to stop when it has processed all the related files in a circular relationship. If omitted, cascading defaults to zero (0). You should always omit this parameter when calling the Open method from your program. |
The Open method Opens this object's primary file (see Me) and any related files, and returns a value indicating its success or failure.
Implementation:
The Open method uses the FileManager.Open method to Open each file. The Open method returns the FileManager.Open method's return value. See File Manager Class for more information.
Return Data Type: BYTE
Example:
Relate:Customer.Open !open Customer and related files
!program code !process the files
Relate:Customer.Close !Close Customer and related files
