+CONCEPT
+        character escape codes
+
+DESCRIPTION
+	Character escape codes are used to represent some common
+	special characters that would be awkward or impossible to
+	enter in the source program directly. The escape characters
+	come in two varieties: 'character escapes', which can be
+	used to represent some particular formatting and special
+	characters, and 'numeric escapes', which allow a character to
+	be specified by its numeric encoding.
+
+	Escapes begin always with a backslash '\'. If the following
+	characters could not be treated as a valid escape the backslash
+	is merely ignored.
+
+	The following character escapes are available in LPC (the code
+	may differ from platform to platform):
+
+	  \a    Code 007    Bell
+          \b    Code 008    Backspace
+          \e    Code 027    Escape
+	  \f    Code 012    Formfeed
+	  \n    Code 010    Newline
+	  \r    Code 013    Carriage-Return
+	  \t    Code 009    Tabulator
+	  \\    Code 092    Backslash itself
+	  \'    Code 039    Single quote
+	  \"    Code 034    Double quote
+
+	The single quote may appear without preceding backslash in character
+	constants, and the double quote may appear without a backslash in
+	string constants.
+
+	The numeric escapes could be used to express a character directly
+	by its code in binary, octal, decimal or hexadecimal notation.
+	
+	  \0b   Beginning of binary notation
+	  \0o   Beginning of octal notation
+	  \0x   Beginning of hexadecimal notation
+	  \x    Beginning of hexadecimal notation
+
+	A backslash followed by a digit ([0-9]) which does not map to one
+	of the above starts an escape in decimal notation.
+
+	A numeric escape terminates when N digits have been used up or
+	when the first character that is not a valid digit in that
+	notation is encountered. N is 2 for hexadeximals, 3 for
+	decimals and octals and 8 for binarys.
+
+	If the specified code is greater than 255 a warning is issued and
+	the value modulo 256 is used.
+
+EXAMPLES
+	Put a newline at the end of user output
+	  "You enter.\n"
+
+	Alert the user
+	  "Beeep.\a Wake up\n"
+
+	Put a double quote in a string
+	  "You say \"hello\"\n"
+
+	Write the line from above
+	  "\"You say \\\"hello\\\"\\n\""
+
+	Put a single quote in a string
+	  "You say 'hello'\n"
+
+	Some forms to write "abcde"
+	  "abcde"
+	  "ab\99de"              (with c's code being 99)
+	  "ab\099de"
+	  "ab\x63de"             (99 = 0x63)
+	  "ab\0x63de"
+
+	The following string consists of two characters
+	  "\0111"                (\011 and 1)
+
+	The following string consists of three characters
+	  "\0o090"               (\000 and 9 and 0)
