Details

SetValueAt can be used to update a value in a list cell.
 
This allows a value to be set without needing to use LANSA list commands such as UPD_ENTRY, and without needing to know the fields being used as the source of a column.
 
The entry must exist in the list before it can updated. If it doesn't, SetValueAt will return a False.

Example

Using SetValueAt. If it fails the code inside the IF will be executed.

   * Update of cell failed
 
Endif
