SEMESS - Called by a user to get a specified portion of the current error message.

       To use SEMESS or c_semess, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably  in
       that order.

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

       #include <ncarg/ncargC.h>

UNIX                                               March 1994                                     SEMESS(3NCARG)

       In any routine that references SEMESS, it must be declared to be of type CHARACTER*113.

       If the internal error flag of SETER is non-zero, the value of the character expression "SEMESS(ITRIM)" is
       the remembered error message associated with that error flag, trimmed as indicated by the value of the
       input quantity ITRIM.  Otherwise, it is a string of blanks.

       When ITRIM = 0 or less, no trimming is done; the whole error message is returned.  When ITRIM = 1,
       prepended routine names and the associated slashes are trimmed off.  When ITRIM = 2 or greater, all
       leading routine names are trimmed off; just the error description is returned.

       Example: Assume that the current error message is the string "CPCLAM/AREDAM - AREA-MAP ARRAY OVERFLOW";
       then, SEMESS(0) is that entire string, while SEMESS(1) = "AREDAM - AREA-MAP ARRAY OVERFLOW", and
       SEMESS(2) = "AREA-MAP ARRAY OVERFLOW".

       The argument of SEMESS is as follows:

       ITRIM       (an  input  expression  of  type  INTEGER)  -  Says  what  part of the error message is to be
                   returned, as detailed above.

       Use the ncargex command to see the following relevant examples: tseter, arex02.
