Help for GTGORE

PURPOSE
     GTGORE is a VICAR applications program which calculates gore
     adjustments for GTWARPXD (see its subroutine GTWRPSUB).  It
     is not intended for general use.
	   
CALL
     gtgore (GRID_A,GRID_B) ACOLS=(C1,C2,C3,C4) BCOLS=(C1,C2,C3,C4)             SLVAR=INCSL SSVAR=INCSS NLVAR=INCNL NSVAR=INCNS
  WHERE:
     GRID_A         is the first grid in GEOMV format.
     GRID_B         is the second grid in GEOMV format.
     ACOLS          are the columns used in the first ibis file.
     BCOLS          are the columns used in the second ibis file.
     SLVAR          is a TAE TCL variable to output the SL increment
     SSVAR          is a TAE TCL variable to output the SS increment
     NLVAR          is a TAE TCL variable to output the NL increment
     NSVAR          is a TAE TCL variable to output the NS increment
     
OPERATION

GTGORE operates like gridcomp except that.

PERFORMANCE

faster than gridcomp

Restrictions
------------

Only a 40 x 40 grid can be input as the second file.  The first file must
be in GEOMV input format.  Both input files are IBIS files.
