■ 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.

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

■ 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).

■ 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
