Guidelines for printing the exchange structure

L.1 Print control directives

The exchange structure allows the optional inclusion of directives that explicitly control a printed representation of the structure. Where such directives are not included but a printed representation of the exchange structure is to be created, the set of implicit print control guidelines specified in G.2 should be used. The explicit print control directives override the implicit print control guidelines.

L.2 Explicit print control directives

Explicit print control directives may be used in those cases where the sender needs accurate control of the printed appearance of the exchange structure.

The directive reverse solidus latin capital letter N reverse solidus "\N\" indicates that the first character immediately following the directive appears at the start of a new printed line. The directive reverse solidus latin capital letter F reverse solidus "\F\" indicates that the printing continues at the start of a new page. In either case, the print control directive itself should not be printed.

NOTE      The printing of the exchange structure will normally not be controlled by the explicit or implicit print control directives. It is assumed that the print control directives will only be used in those circumstances where the sender requires control over the printed appearance of the exchange structure. This situation may occur if the exchange structure is part of a legal contract.

L.3 Implicit print control directives

When printing the exchange structure, the following directives may be used in the absence of explicit print control directives:
