Re: NULL terminated strings

[Raul Jager <raul@xxxxxxxxxx>]

NULL means different things in various contexts.

In a DataBase NULL means the column has no value for this row.
In ASCII it means a byte that has a value of 0 (zero)
NULL terminated strings use the ASCII NULL as an indicator to mark the
end.
  This is widely used in C and Assembler.
