Expressions and assignment statements are the fundamental means of computation in imperative languages. An expression is any statement that can legally appear on the right side of an assignment statement.
Understanding assignment statements and expressions help you write effective C/AL code. Explain the concepts of assignment, statement, and assignment statement. Describe the syntax of statements and introduce the statement separator. Describe automatic type conversions for string, numeric, and other data types.
