TCHK (v2.10) by Howard Kapustein                 REGISTRATION ($20.00)
  Distributed as TCHK21.SDN, TCHK21EX.SDN, TCHK21NG.SDN

TCHK is a Turboc C library compiled with Turbo C 2.0 sporting over
350 functions. Some of these functions are:

- litebar and popup style menus            - mouse info and control
- keyboard input and video output/control  - DOS disk and file functions
- date, time and string manipulations      - math and financial functions
- hardware and software identification     - printer control functions
- multi-tasking functions                  - joystick functions

TCHK  sports  many  useful  features  not  found  in  other  shareware
packages.  Aside from  many input and  output routines, TCHK  provides
many functions dealing  with dates, time,  strings, popup and  litebar
menus, DESQview support, and much more.

Many  of  the  functions  requiring  output  as  a  side  effect (most
noticeably the keyboard  and menu functions)  make use of  some of the
output  routines  prototyped  in  VIDEO.H  or  some of the console i/o
functions by Borland (i.e. cputs(), putch(), etc.).  If you use almost
any of the  keyboard routines, also  expect some video  routines to be
linked into  your program.   This is  true of  some other functions as
well (the popup menus  use Borland's gettext() and  cputs() routines.)
If you really want to change the library, you can always purchase  the
source code...

Hardware Requirements:  Except where  explicitly stated,  all of these
functions  have  been  compiled  and  tested  on  the  authors system.
