p1 -- Number of times to repeat the section.
p2 -- Macro(name) to advance with each repetition (optional).
In order that the sections may be more flexible than simple editing, the macro named p2 is given the value of 1 for the first time through the section, 2 for the second, and 3 for the third. This can be used to change p-field parameters, or ignored.
Warning |
Because of serious problems of interaction with macro expansion, sections must start and end in the same file, and not in a macro. |
In the following example, the section is repeated 3 times. The macro NN is used and advanced with each repetiton.
