[ 2 ] Statements
Statements can come in two types: executable and declarative statements.
• Executable statements
They make the Interpreter process programs by instructing the operation to be executed.
• Declarative statements
They manage the memory allocation for variables and handle comments. Declarative
statements available in BHT-BASIC are listed below.
REM
or single quotation mark (’)
DATA
COMMON
DEFREG
Multi-statements:
You can describe multiple statements in one program line by separating
them with a colon (:).
[ 3 ] Comments
A single quotation mark (’) or
REM
can begin a comment.
• Single quotation mark (')
A single quotation mark or apostrophe (’) can begin in the first column of a program line
to describe a comment.
When following any other statement, a comment starting with a single quotation mark
requires no preceding colon (:) as a delimiter.
