This allows you to modify pointer variables during +debugging. (In standard Modula-2, the actual address contained in a +pointer variable is hidden from you; it can only be modified +through direct assignment to another pointer variable or expression that +returned a pointer.) + +</li><li> C escape sequences can be used in strings and characters to represent +non-printable characters. <small>GDB</small> prints out strings with these +escape sequences embedded. Single non-printable characters are +printed using the ‘<samp>CHR(<var>nnn</var>)</samp>’ format. + +</li><li> The assignment operator (<code>:=</code>) returns the value of its right-hand +argument. + +</li><li> All built-in procedures both modify <em>and</em> return their argument. +</li></ul> + + + + +</body> +</html> |
