Software Structure
System Program and JIS Level 1 &Level 2 fonts are resident in the system area and user area,
respectively.
To use extension programs and user programs, you should download the program files into the user
area.
To use data files (e.g., good master files) required for execution of user programs, you should download
those data files before execution of user programs. Those files will be stored in the user area.
System Programs
The system programs include the following three sets of programs:
Drivers
Drivers is a set of programs that directly controls the BHT hardware. It may be called up by the
BHT-BASIC Interpreter or System Mode.
BHT-BASIC Interpreter
The interpreter interprets and executes instructions in user programs written in BHT-BASIC.
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).
