.Ss Block Macros

Block macros are comprised of a head and body. Like for in-line macros,

the head is scoped to the current line and, in one circumstance, the

next line; the body is scoped to subsequent lines and is closed out by a

next line (the next-line stipulations as in

subsequent block macro invocation.
