r p1 p2
Starts a repeated section, which lasts until the next s, r or e statement.
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.
r3 NN ;start of repreated section - use macro NN some code . . . s ;end repeat - go back to previous r if repetitions < 3
