System Mode
System Mode is a system program exclusively designed for the effective use of user
programs in the BHT. It sets up the execution environments for those programs; e.g.,
it prepares downloading/uploading conditions, sets the calendar clock, and tests the
BHT components including the LCD, beeper, and keypad. Shown below is the System
Mode menu (SYSTEM MENU).
■ JIS Level 1 and Level 2 Font Files
These files contain font data required for displaying Kanji characters on the LCD.
The BHT can display the Kanji characters not only in the conventional standard-size
font (16 dots wide by 16 dots high) but also in the small-size font (12 dots wide by 12
dots high) in application programs. It can also display the double-width, double-
height, and quadruple-size (double-width & -height) Kanji characters of those 16-dot
and 12-dot fonts in application programs.
If you do not need to display Kanji characters, you may delete these JIS font files.
After deletion, the memory area which was occupied by these files can be used as a
user area. For the deleting procedure, refer to Section 2.4, "Initializing the BHT
System" or Subsection 2.5.3, "[ 7 ] Deleting Files."
The names of the JIS font files are:
FNT16J1.FN3 (JIS Level 1 font, 16-dot)
FNT16J2.FN3 (JIS Level 2 font, 16-dot)
FNT12J1.FN3 (JIS Level 1 font, 12-dot)
FNT12J2.FN3 (JIS Level 2 font, 12-dot)
■ User Programs
You can develop application programs to meet individual job requirements by using
the BHT-BASIC Compiler. To download those user programs to the BHT, use Ir-
Transfer Utility C/Ir-Transfer Utility E/Transfer Utility.
