4.6.6.3 Formatted Output

format([Stream,] Control, Arguments) interprets the Arguments according to the Control string and prints the result on the current or given output stream. Alternatively, an output stream can be specified in an initial argument. This predicate is used to produce formatted output, like the following example.

| ?- toc(1.5).
Table of Contents                                               i
