Firebird supports two types of comments: block and in-line.

    Block comments start with the character pair and end with the */ character pair. Text in block comments may be of any length and can occupy multiple lines.

    Example

    1. CREATE PROCEDURE P(APARAM INT)
    3. BEGIN
    4.   /* This text will be ignored during the execution of the statement
    5.   */
    6.   B = A + 1; -- In-line comment
