  BHT - Basic 4.0 Development Pack

A software package required for the development of BHT applications

  • BHT-BASIC4.0 Development Pack
  • BHT-BASIC4.0 Up GradePack

Each region has different availability of sales product.

The Trial Edition of this software can be downloaded from QBdirect.

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.

  • 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).

Extended Basic Program Elements

Program Increased to 3,2767 from 8,192 characters per line
Number of program lines is increased to 32,767 from 9,999
Program size is increased to 2 GB max. from 128 KB(1) max. (However, it depends on the memory size of BHT.)
Label Number of characters is increased to 255 from 10 characters
Identifier Number of characters is increased to 255 from 10 characters
Number of available identifiers is increased to 1,024 from 255 for each variable type
  1. 64 KB program cord + 64 KB register variable
