   Notes:

      This file contains function prototypes for all appropriate routines used
      in this application.

   Revision history:

      4.10.0
            B.Marr            2006-07-19
            
            Broke 'pcalglob.h' up into 2 parts.  The actual declarations
            are now in 'pcal.c'.  The external references were put in this
            file along with the necessary function prototypes for
            functions defined in 'pcal.c'.
            
            Reformatted comments and code to match my standards.
            
            B.Marr            2006-07-12
            
            Get rid of all the '#ifdef PROTOS' checks, which are pretty
            much obsolete these days and just needlessly clutter up the
            code.
            
      4.9.0
            B.Marr            2005-08-02
            
            Add prototype for new function 'delete_day_info()' and rename
            'enter_date()' to 'process_date()', all based on a patch from
            Bill Bogstad.

      4.8.0
            B.Marr            2004-12-03
            
            Add prototype for new function 'recalc_paper_parameters()'.
            
            B.Marr            2004-11-13
            
            Add prototypes for new functions 'do_define_sym_val()',
            'find_sym_val()', 'find_fri13th()', and
            'recalc_paper_parameters()'.  Rename 'find_sym()' to
            'find_sym_name()' to avoid search collisions with new
            function.

      4.7   AWR   06/19/1998  add multiple_months_html() and
                              single_month_html() (cf. writefil.c)

                  02/24/1998  add prototypes for exit() and free()
                              if not already included via <stdlib.h>

                  07/27/1997  add print_html(), write_htmlfile() (cf.
                              writefil.c) and set_fontstyle() (cf.
                              pcalutil.c)

      4.6   AWR   05/14/1997  add century() (cf. pcalutil.c)

                  10/31/1995  add gen_lang_sym() (cf. pcal.c)

                  10/03/1995  revise write_psfile, write_calfile()
                              (cf. writefil.c)

                  09/21/1995  add enter_date(), enter_date() (cf.
                              readfile.c)

      4.5   AWR   11/24/1993  replace find_holidays() with
                              print_colors() (cf. writefil.c)

                  11/16/1993  added new routines define_font(),
                              define_shading() (latter replaces
                              old gen_shading()), and set_rgb()

                  11/16/1992  eliminated "noprotos.h" by means of
                              PROTO() macro (q.v.)

      4.4   AWR   01/15/1992  added even more routines

      4.3   AWR   12/06/1991  added more routines

      4.2   AWR   10/03/1991  added various routines newly
                              incorporated into writefil.c
                              and pcalutil.c

      4.0   AWR   03/01/1991  use <stdlib.h> where possible

                  02/19/1991  adapted from Bill Hogsett's source
