Conditional statements

Conditional statements are the heart of process flow structure and control.

The BEGIN–END compound statement

In C/AL, there are instances where the syntax only allows for use of a single statement. But a design may require the execution of several (or many) code statements.

C/AL provides at least two ways to address this need. One method is to have the single statement call a function that contains multiple statements.

However, inline coding is often more efficient to run and to understand. So C/AL provides a syntax structure to define a Compound Statement or Block of code. A compound statement containing any number of statements can be used in place of a single code statement.

A compound statement is enclosed by the reserved words BEGIN and END. The compound statement structure looks like this:

BEGIN
  <Statement 1>;
  <Statement 2>;
  ..
  <Statement n>;
END

The C/AL code contained within a BEGIN – END block should be indented...
