File:DatasetCallback
Purpose:Enum for ProDataset Callback Names
Description:Reduce risk of typos in ProDataset SET-CALLBACK method
Author(s):Mike Fechner / Consultingwerk Ltd.
Created:Mon May 09 08:31:24 CEST 2011
Notes:Enum names are without - for consistency with coding stlye
However the values will return the proper form ABL constant
including the dash ("-")
This Enum type is purposely implemented using CHARACTER
static properties and not our Enum base class / EnumMember.i
include file - because the SET-CALLBACK method does implicitely
use the ToString() method and thus would cause compilation
issues.
