8.4.1 Creation of Execution File
Application developers should develop programs using various application development libraries.
The following sample program is used to turn on and off the backlight. With this program the
backlight will be turned on or off if either "1" or "0", respectively, is entered through the numeric
keypad. This program can be terminated by the input of the ESC key.
The following program shows only a part of the whole program which controls the backlight in the
Windows Procedure.
#include <windows.h>
#include “syslib.h”
....
case WM_CHAR:
switch (ch = wParam) {
case '0':
case '1':
SYS_SetBackLight(ch - ‘0’); /* System Library function */
default:
break;
}
}
....
Next, create the execution file with the following procedure.
This example assumes that the SDK of the IT-2000 has been installed in C:
 IT-2000. If it is
installed in another directory, it is necessary to designate the location in which to store the header
file and library file according to the development environment. These designation can be made
using the environment variables INTCLUDE and LIB.
For more information refer to a compiler manual published separately by a third party.
