 ; The following code is used to identify any pairs which have a same internal number in them and to
 ; exclude any after the first occurence of the internal number from the current merge
 ; the first occurrence is that based on the lowest ien for the FROM entry and the lowest ien for a
 ; TO entry associated with it.  Any other pairs involving either of these iens is then excluded.
 ;
 ; The XDRBROWSER1 device is used to capture any output generated due to exclusion of pairs and is
 ; then sent as a mail message.
