BHT-BASIC4.0 Development PackA software package required for the development of BHT applications
| Model |

| 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.
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.
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.
Data file sizes are extended to meet large volumes of data.
| Maximum number of records | Increased to 2G from 32,767 records (equivalent to a maximum No. of long integer) |
|---|---|
| Maximum record length | Increased to 65,535 from 255 bytes |
| Field variable size | Increased to 8,192 from 255 characters (equivalent to a maximum length of character string) |
| Number of fields | Increased to 254 from 16 fields |
To gain access to a large amount of storage, types of variables are extended. You can use extended versions of variables on the BHTs.
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).
Programming is simple and easy as a result of increase in the following element sizes.
| 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 |
