16System ModeSystem Mode is a system program exclusively designed for the effective use of userprograms 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 theBHT components including the LCD, beeper, and keypad. Shown below is the SystemMode menu (SYSTEM MENU).■ JIS Level 1 and Level 2 Font FilesThese 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-sizefont (16 dots wide by 16 dots high) but also in the small-size font (12 dots wide by 12dots high) in application programs. It can also display the double-width, double-height, and quadruple-size (double-width & -height) Kanji characters of those 16-dotand 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 auser area. For the deleting procedure, refer to Section 2.4, "Initializing the BHTSystem" 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 ProgramsYou can develop application programs to meet individual job requirements by usingthe BHT-BASIC Compiler. To download those user programs to the BHT, use Ir-Transfer Utility C/Ir-Transfer Utility E/Transfer Utility.
