Write one line of text to an open file in the files/ folder. This is a method of the \c;\l;file\u cbot\file;\n; class. This is the reason why we always write \c;handle.writeln()\n;¦:
\c;
\s; handle.writeln("abc");
\n;
The file must have been opened for writing (\c;"w"\n;) with the \c;\l;open\u cbot\open;\n; instruction. The line will automatically be terminated by the end of line characters 0x0D (CR) and 0x0A (LF).
