The notation mentioned was originally used in the C programming language but is
also available in Perl, java, C++ and several other languages. slash followed
by a character is used for tabs and new lines and other frequently used ascii
characters. slash followed by a two diget number represents the character as a
decimal number. If the first character after the slash is 0 then the number is
in base 8 instead of decimal, and if the first two characters are 0x then it
represents a hexidecimal number.
The rest you should be able to find in many programming guides.
