The irony of this is that the manufacturer's (IBM's) character set (EBCDIC)
*does* include codes for "[" and "]", it's just that a lot of their
equipment doesn't quite support their own character set.

The pre-ANSI method used in the SAS C compiler ("(|" for "[" and
"|)" for "]") strikes me as far more readable, and neither combination
is otherwise legal C.
