public function integer of_SetReqColumn (boolean ab_switch);//////////////////////////////////////////////////////////////////////////////
//	Public Function:  of_SetReqColumn
//	Arguments:		boolean
//   					true  - Start (create) the service
//   					false - Stop (destroy ) the service
//	Returns:			Integer - 1 if Successful operation, 0 = No action taken and -1 if an error occured
//	Description: 	Starts or stops the Required Column Service.
//						This service allows users to Tab/Click out of Required fields without entering any data.
//
//						Through the DataWindow ItemError Event the service (if appropriate) will replace an empty
//						string with a null value and surpress the standard DataWindow "Value Required For This Item Message".
//						The one requirement for this behavior is that the RequiredField is also set to accept "empty string
//						as a null".  The end result of this action is that an user can click or Tab out of a Required field
//						without first having to enter data in it. Note: The RowStatus and ItemStatus of the field is not 
//						affected/changed by the service.
