PARSE(ARRAY) ;PARSING OF VERSION 1.5 TRANSMISSION
 ;INPUT  : ARRAY - Parsing array (full global reference)
 ;         (As defined by MailMan)
 ;         XMFROM, XMREC, XMZ
 ;         (Declared in SERVER^VAQADM2)
 ;         XMER, XMRG, XMPOS
 ;OUTPUT : XMER - Exit condition
 ;           0 = Success
 ;           -1^Error_Text = Error
 ;         XMPOS - Last line [number] read in transmission
 ;                 (if NULL end of transmission reached)
 ;NOTES  : Parsing array will have the following format
 ;           ARRAY(MessageNumber,BlockName,BlockSeq,LineNumber) = Value
 ;          [BlockSeq used to keep blocks of same name from
 ;           overwritting each other.  This will typically be '1'
 ;           except for DATA & DISPLAY blocks.]
 ;          [MessageNumber is not XMZ ... it denotes the message
 ;           number withing the transmission]
 ;       : Calling routine responsible for ARRAY clean up before
 ;         and after call
