Function

The BEFORE BREAK PROCESSING statement may be used in conjunction with automatic break processing to perform processing:

This statement is most often used to initialize or compute values of user-defined variables which are to be used in break processing (see AT BREAK statement).

This statement is non-procedural (that is, its execution depends on an event, not on where in a program it is located).

Statement(s) for Break Processing:
In place of statement, you must supply one or several suitable statements, depending on the situation. For an example of a statement, see Example below.

If no break processing is to be performed (that is, no AT BREAK statement is specified for the processing loop), any statements specified with a BEFORE BREAK PROCESSING statement will not be executed.

END-BEFORE
End of BEFORE BREAK PROCESSING Statement:
In structured mode, the Natural reserved word END-BEFORE must be used to end the BEFORE BREAK PROCESSING statement.
