\b;Instruction \c;open\n; Open a text 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.open()\n;¦: \c; \s; handle.open("test.txt", "w"); \n; To open a file, proceed as follows¦: \c; \s; file handle(); \s; handle.open("filename", "w"); \s; handle.writeln("abc"); \s; handle.close(); \n; \c;"r"\n; mode: open for reading. \c;"w"\n; mode: open for writing.
