Escape Sequences for Non-Printable ASCII Characters

This section describes escape sequences for non-printable ASCII characters in 'string' literals.

The following escape sequences need to be supported to allow us to enter non-printable characters in string literals:

Both upper case and lower case of hexadecimal digits are supported.

Examples of "string" literals with escape sequences for non-printable ASCII characters:

write("Leave a message after the beep: \x07.");

write("Backspace key to remove letter A\x08."); 

write("What is the null character \x00 for?"); 

write("\x0a is the same as \n."); 

write("\x0A is the same as \n.");
