1.3 Program Development and Execu-

tion

BHT-BASIC consists of Compiler and Interpreter.

1.3.1 Compiler

BHT-BASIC 3.5 Compiler consists of the following Compiler, Linker and Librarian:

■

Compiler

Compiler, which is one of the development tools, compiles source programs written on a PC

into the resulting "object files."

It checks syntax of source programs during compilation and makes an error file if any syntax

error is found.

■ Linker

Linker, which is one of the development tools, combines object files (translated by Compiler)

together to build a "user program" in the intermediate language.

If linking does not end normally, Linker makes an error file.

■

Librarian

Librarian, which is one of the development tools, builds "library files" out of object files trans-

lated by Compiler.

If Librarian does not end normally, it makes an error file.

1.3.2 Interpreter

Interpreter interprets and executes a user program downloaded to the BHT, statement by state-

ment.
