Question

I have a file test.sql with:
DECLARE
    x varchar(4000);
BEGIN
    x := 'my test
# line error 1
@ line error 2
end of test';
    dbms_output.put_line(x);
END;at sqlplus i run it like this
SQL>@test.sql
SP2-0734: unknown command beginning "line error..." - rest of line ignored.
SP2-0310: unable to open file "line.sql"
  8  How can I make sqlplus ignore # and @?
Add --@ or --# does not solve my problem, because its part of a text.

It is the @ that is the problem.
Put an escape character (default \) before the @ or set a new escape char.
See SET ESCCHAR in the SQL*PLUS doc

SET ESCCHAR {@ | ? | % | $ | OFF}
Specifies a character to be escaped and not interpreted when used in a file name for
the SPOOL, START, @, RUN and EDIT commands. These special characters are
translated to the following:
■ @ in a filename will be translated to Oracle SID
■ ? is translated to Oracle Home in Unix
■ % is translated to Oracle Home in Windows
■ $ is translated to Oracle Home in certain platforms
While it is not recommended that these characters are used in filenames, if you have
legacy files that do use them, it might be useful to include a SET ESCCHAR command
in your GLogin file to implement it across your site.
If not escaped, the characters @, ?, % and $ have significance when interpreted and
cause errors for the SPOOL, START, @, RUN and EDIT commands.
SET ESCCHAR is set OFF by default.
Example
If you include the character ’$’ in your filename, then
SET ESCCHAR $
RUN MYFILE$
behaves normally.
