Environment

Items Requirements

CPU Pentium 75MHz

Operating System Windows 95/98/2000/NT/XP

Minimum RAM 16 MB

Minimum Hard Disk Space 20 MB

Note: Any terminal being programmed will need to have a minimum 128KB RAM.

2.3 BASIC Run-time Engine

The BASIC Run-time Engines work as interpreters of the BASIC commands. Terminals

have to be loaded with the BASIC Run-time Engines to run the BASIC programs. Each

model of terminal has its own Run-time Engine to drive its specific hardware features. The

Run-time Engines are named as "BCxxx.shx", where "BCxxx" is the model number of the

target terminal.

The BASIC Run-time also provides the capabilities for the user to configure the terminal.

With the Run-time Engine loaded, the terminal can be set to the "System Mode". In the

"System Mode", the user can set up the system settings such as the system clock and update

the user program and so on. To enter the "System Mode", just press 7, 9 and POWER keys

simultaneously. The System Menu presented in the "System Mode" varies for different

models of terminals. For detailed functions of the System Menu, please refer to the user

manual of the terminal.

2.4 Development Flow

Developing a BASIC program for terminals is as simple as counting 1-2-3. There are three

steps:

1 2 ... 6 7 8 9 10 11 12 13 14 15 16 ... 197 198
