Software Tool for Developing Applications

This BHT-BASIC4.0 Development Pack contains the complete software programs required for developing applications for the BHT Series scanners. You can start a development at right using the provided software and accessory products described below.

• BHT-BASIC 4.0 Compiler (including BHT-BASIC3.6)
• BHT-BASIC 4.0 Remote Debugger (debugging BHT-BASIC3.6 is enabled)
• BHT-BASIC 4.0 Transfer Utility (including BHT-Ir protocol)
• PC-BHT cable (RS232C)

Easy-To-Develop Programming Language

Since a BASIC language based on the Microsoft MS-BASIC ideal for handy terminals is used, this development package offers features unique to a barcode reader just with one command. Included in the package are commands and functions exclusively used for barcode reading and data reception/transmission. Since this BHT-BASIC operates in the interpreter environment, reliable operation free from expected failures such as breakdown or memory destruction caused by a potential programming error is realized.

Expanded Functions

Basic elements of conventional BHT-BASIC3.6 programs, such as a size of program and data file, variable and label length, are largely extended, which all together will help give much more flexibility in developing a program. ⁽¹⁾

High Compatibility

You can compile a source program written by BHT-BASIC3.x without a change using the BHT-BASIC4.0 compiler. ⁽²⁾

1. However, these expansions apply only to the BHT-300 Series scanners. The BHT-7000/BHT-7500/BHT-8000/BHT-100 Series still use the existing BHT-BASIC3.6 basic elements.
2. Note that programs that rely on the hardware, such as communication speed, should be appropriately modified.

Basic Features of BHT-BASIC4.0

The BHT-BASIC4.0, an extended version of BHT-BASIC3.6, has been enhanced to support even a larger file size and program size. In addition, its enhanced variable scope and valid duration combined with a wide range of selectable user-defined functions have increased the efficiency of program development.

In the BHT-BASIC4.0A, an execution program has a .PD4 type extension, instead of a .PD3 type conventionally adapted in BHT-BASIC3.x.

Operating Environment of BHT-BASIC4.0 (Supported BHTs)

The executable programs (PD4) complied by the BHT-BASIC4.0 Development Pack are designed to operate on the BHT-300 Series scanners equipped with a system compatible with BHT-BASIC4.0. They do not run on the BHT scanners, such as BHT-8000 Series, equipped with the conventional BHT-BASIC3.x-supported systems.

Any source programs written by BHT-BASIC4.0 cannot be complied in the BHT-BASIC3.6 configuration.

Wide Selections of Data File Sizes

Data file sizes are extended to meet large volumes of data.

Extended Variable Types

To gain access to a large amount of storage, types of variables are extended. You can use extended versions of variables on the BHTs.

• Supporting long integers
• A maximum length of character string is significantly increased from 255 to 8,192 characters

Enhanced Variable Scope/Valid Duration

The scope of variable, a range in which the variable can be referred to, is enhanced to make it explicitly definable (PUBLIC statement).

In addition, controlling the valid duration of each variable, or a period the variable remains valid, specified in the user-defined function is possible (DIM, PRIVATE and STATIC statements).
