Whenever I type the @ sign like for example when using a proxy ftp server, The system forces the cursor to jump to a new line. I know it has something to do with the terminal settings.

erl_comment_scan(3erl) Erlang Module Definition erl_comment_scan(3erl)NAME
erl_comment_scan - Functions for reading comment lines from Erlang source code.
DESCRIPTION
Functions for reading comment lines from Erlang source code.
DATA TYPES
comment() = {integer(), integer(), integer(), [string()]} :
EXPORTS
file(FileName::filename() (see module file)) -> [Comment]
Types Comment = {Line, Column, Indentation, Text}
Line = integer()
Column = integer()
Indentation = integer()
Text = [string()]
Extracts comments from an Erlang source code file. Returns a list of entries representing multi-line comments, listed in order of
increasing line-numbers. For each entry, Text is a list of strings representing the consecutive comment lines in top-down order; the
strings contain all characters following (but not including) the first comment-introducing % character on the line, up to (but not
including) the line-terminating newline.
Furthermore, Line is the line number and Column the left column of the comment (i.e., the column of the comment-introducing % char-
acter). Indent is the indentation (or padding), measured in character positions between the last non-whitespace character before the
comment (or the left margin), and the left column of the comment. Line and Column are always positive integers, and Indentation is a
nonnegative integer.
Evaluation exits with reason {read, Reason} if a read error occurred, where Reason is an atom corresponding to a Posix error code;
see the module file(3erl) for details.
join_lines(Lines::[CommentLine]) -> [Comment]
Types CommentLine = {Line, Column, Indent, string()}
Line = integer()
Column = integer()
Indent = integer()
Comment = {Line, Column, Indent, Text}
Text = [string()]
Joins individual comment lines into multi-line comments. The input is a list of entries representing individual comment lines, in
order of decreasing line-numbers ; see scan_lines/1 for details. The result is a list of entries representing multi-line comments,
still listed in order of decreasing line-numbers , but where for each entry, Text is a list of consecutive comment lines in order of
increasing line-numbers (i.e., top-down).
See also: scan_lines/1 .
scan_lines(Text::string()) -> [CommentLine]
Types CommentLine = {Line, Column, Indent, Text}
Line = integer()
Column = integer()
Indent = integer()
Text = string()
Extracts individual comment lines from a source code string. Returns a list of comment lines found in the text, listed in order of
decreasing line-numbers, i.e., the last comment line in the input is first in the resulting list. Text is a single string, contain-
ing all characters following (but not including) the first comment-introducing % character on the line, up to (but not including)
the line-terminating newline. For details on Line , Column and Indent , see file/1 .
string(Text::string()) -> [Comment]
Types Comment = {Line, Column, Indentation, Text}
Line = integer()
Column = integer()
Indentation = integer()
Text = [string()]
Extracts comments from a string containing Erlang source code. Except for reading directly from a string, the behaviour is the same
as for file/1 .
