753 Convert special characters in strings back to their escaped forms. For\n\ |

| 757 bell = \"\\a\";\n\ | |
| 758 @end example\n\ | |
| 759 \n\ | |
| 760 @noindent\n\ | |
| 761 assigns the value of the alert character (control-g, ASCII code 7) to\n\ | |
| 762 the string variable @code{bell}. If this string is printed, the\n\ | |
| 763 system will ring the terminal bell (if it is possible). This is\n\ | |
| 764 normally the desired outcome. However, sometimes it is useful to be\n\ | |
| 765 able to print the original representation of the string, with the\n\ | |
| 766 special characters replaced by their escape sequences. For example,\n\ | |
| 767 \n\ | |
