 ;File Order List for Resolving Pointers
FOLRP(DIFRFLG,DIFRTA) ;FLAGS,TARGET_ARRAY ; Creates the "DIORD" subscript
 ;                structure in the transport array.
 ;FLAGS,TARGET_ARRAY

 ;FLAGS = None
 ;*
 ;TARGET_ARRAY = CLOSED ROOT
 ;               This is the Transport Array Root.
 ;               "DIORD" is appended to the array root.
 ;               A ordered list of files is returned
 ;               in the target array.  Each file is given
 ;               a value to determine which file should have
 ;               pointers resolved.  After each file has been
 ;               assigned a value it is ordered by value then
 ;               by file number.  If files have the same value
 ;               the file number is then used to determine the
 ;               order.  This call is used after all the file
 ;               being transported are in the "FIA" structure.
