PROCACK(HLMTIEN,HLEID,HLRESLT,HL) ;Process acknowledgement message
 ;
 ;This is a subroutine call with parameter passing.  It returns a value
 ;in the variable HLRESLT of null if no error occurs, or the following
 ;two piece value if an error occurs:  error code^error description
 ;
 ;Required Input Parameters
 ; HLMTIEN = The IEN from the Message Text file created when the
 ;             GENERATE^HLMA or SEND^HLMA2 entry points were invoked
 ;   HLEID = The IEN from the Protocol file of the driver event
 ;NOTE:  The variable HLRESLT must be passed by reference
 ; HLRESLT = The variable that will be returned to the calling
 ;             application as descibed above
 ;Optional Input Parameter
 ;      HL = An array of variables to be used in processing the message
 ;
 ;Check for required parameters
