GLOBAL VARIABLES
These variables are defined for one reason or another and used
internally. None of these variables have to be initialized (see
insertmode.) They are mainly used to return extra values found in
certain functions or needed globally by other functions.
Date variables:
char *Days[7] = { "Sunday","Monday","Tuesday","Wednesday",
"Thursday","Friday","Saturday" };
char *Months[12] = { "January","February","March","April",
"May","June","July","August",
"September","October","November",
"December" };
char *MonthAbbr[12] = { "Jan","Feb","Mar","Apr","May",
"Jun","Jul","Aug","Sep","Oct",
"Nov","Dec" };
int daylist[13] = { 0, 31, 59, 90, 120, 151, 181, 212,
243, 273, 304, 334, 365 };
Note: daylist is a list of the day number of the year at the end
of each month (i.e. April 1st is the 91st (Mar 31 = 90, +1)
day of the year.)
Keyboard variables:
boolean key_extended; /* TRUE if special key pressed,
i.e. Alt-X, etc. */
int key_status; /* shift key status byte */
Note: these variables are set by getk(), and are checked by many
other keyboard routines.
boolean insertmode; /* insert or overwrite mode? */
Note: This variable is used internally by getstr() and getget().
Although getget() initializes this variable, getstr does
NOT. You MUST set insertmode to TRUE or FALSE before
calling getstr() or unpredictable results may occur. Upon
completion of this function, testing this variable will
determine the input mode last used. Future versions will
default insertmode to some value if it has not been set.
unsigned _cursorinsert;
unsigned _cursoroverwrite;
Note: Cursor used in insert and overwrite modes during keyboard
input. Currently only supported by getget().

TCHK version variables:
unsigned int _TCHKversion = 0x0210;
unsigned char _TCHKmajor = 2;
unsigned char _TCHKminor = 10;
char *_TCHKdate = "06/06/89";
char *_TCHK = "TCHK is Copyright (C) 1988,1989 by Howard
Kapustein. All rights reserved.";
Video variables:
FRAMES: see video.h for frame[] declarations.
const char emptystring[] = " ";
Note: Do NOT alter this variable. emptystring[] is defined
as a string of 15 spaces and is used internally by
several functions. Altering this function can lead to
wildly unpredictable results.
byte char_attribute;
Note: This variable is used by many output functions to set
the attribute byte. For functions such as putstr() you
can either call set_color() with the attribute desired
or declare char_attribute as an extern and then set it
yourself.
