If the continuation character (-) is the last non-blank character
on a line, or the last before the comment character, then the next line of
input will be treated as logically concatenated to the current line. For
terminal input, the user will receive a prompt ``->" indicating that the
line is treated as a continuation. Note that the continuation character
is NOT a delimiter, and thus must be separated from any earlier argument
by a blank or some other delimiter. Examples:
These two lines - are really one line !with 7 arguments This line is not concatenated- !the 5th argument is "concatenated-" with the next. Even if you concatenate -!you are allowed to have comments on each input line ! this was equivalent to an 8 argument line.Because of the way continuations are processed, the user may not see the prompt until the program processes the last argument on the line. Thus, the type-ahead for the continuation may be `invisible'.
