Help for GEOM

PURPOSE

 GEOM is a general purpose procedure that frees the user from the
 burden of selecting which specific geometric transformation program
 is most appropriate for the picture at hand. It tries to run MGEOM
 first as MGEOM is considerably faster and somewhat more accurate.
 If MGEOM fails to work on the picture because the transformation as
 defined by the tiepoints is too complicated (e.g. large rotation or
 pretzel bend), then LGEOM is attempted which should be able to handle
 any case, albeit slowly.
CALLING SYNTAX:

 GEOM   (PIX [,TIE])   (GEO [, IDS)   PARAMS

 where PIX is the input image, TIE is an optional tiepoint dataset,
 (which can only be used by LGEOM), GEO is the geometrically transformed
 output, and IDS is a scratch file that may be used by MGEOM.  Note that
 the scratch file used by LGEOM is supplied via the parameter IDSNAM.

 PARAMS are user parameters that are described further under Tutor Help
 mode.

 The user is referred to the Help for MGEOM and LGEOM for information on
 how these operate.

               Comment out MGEOM because MGEOM is not working, once 
               MGEOM is fixed, need to remove the comment in this proc.
