GOAL:
How to store a HANDLE or WIDGET-HANDLE in a database
FIX:
Store the HANDLE as CHARACTER by using the STRING function. Convert it to a back HANDLE with the WIDGET-HANDLE() function.
Keep in mind that the scope of a handle or widget-handle is the running 4GL session. Storing a handle in a database does not make sense; it should better be stored in a TEMP-TABLE.
Note that the distinction is made between HANDLE and WIDGET-HANDLE just to make the code more readable (widget GUI objects versus non-visible objects) but both can be used interchangeably. They are effectively the same data type.
