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.
