       ENLEVE  - DELETES UP TO FOUR VARIABLES FROM A FILE 
  
 
      AUTHOR  - R.Laprise, NOV 07/83.
      LAST REVISION: $Header: /home/cvs/RMNLIB/utils/rdiag/lspgm/enleve.ptn,v 4.15 2014/09/25 20:20:47 dugas Exp $
  
 
      PURPOSE - DELETES RECORDS FROM FILE IN FOR ALL TIMESTEPS AND LEVELS 
                BETWEEN REQUESTED INTERVALS THEN PUTS THE RESULT ON FILE OUT. 
 
      NOTES   - 1) LABEL RECORDS ARE IGNORED (PASSED DIRECTLY TO FILE OUT).
                2) STEP NUMBERS ARE ASSUMED TO BE INCREASING. 
  
 
      INPUT FILE... 
       IN  = FILE TO BE COPIED. 
             (THIS FILE MUST BE ORDERED BY TIMESTEP NUMBER) 
  
      OUTPUT FILE... 
       OUT = FILE COPIED FROM IN WITH DELETIONS. 
  
 
      INPUT PARAMETERS... 
  
       NT1,NT2 (t1,t2) = TIMESTEP INTERVAL TO BE DELETED, (INCLUSIVE). 
       INT      (t3)   = DATA IS DELETED EVERY INT STEPS FROM STEP NT1. 
       LV1,LV2         = LEVEL INTERVAL TO BE DELETED (LV2 >= LV1).
                         IN COMMAND-LINE MODE, LV1 AND LV2 MAY ALSO BE THE REAL
                         DECODED LEVEL VALUES. IN THAT CASE, THE KIND PARAMETER
                         *** ABSOLUTELY HAS TO BE SPECIFIED ***.
       KIND            = VERTICAL LEVEL TYPE. ONLY USE THIS WITH IN RPN STD FILES
                         AND WHEN LV1 AND LV2 CONTAIN DECODED VALUES. FURTHERMORE,
                         THIS PARAMETRE CAN ONLY BE SPECIFIED IN COMMAND-LINE MODE.
                         THE CURRENTLY SUPPORTED VALUES ARE:
                         'HAUTEUR'   , heights (m) with respect to sea level
                         'SIGMA'     , classical terrain following (0.0 -> 1.0)
                         'ETA'       , first version of the GEM ETA coordinate
                         'PRESSION'  , pressure (mb)
                         'ARBITRAIRE', arbitrary level (no units apply)
                         'HAUTEURS'  , heights (M) with respect to the surface
                         'HYBRIDE'   , hybrid GEM coordinate
                         'THETA'     , potential temperature coordinate
                         'GALCHEN'   , GalChen generalized coordinate
       NAME1,...,NAME10= NAMES TO BE DELETED, OF WHICH ONLY THE FIRST FOUR CAN
                         BE DEFINED USING INPUT CARD INPUT.
