I'd say your "String" is null-terminated. This means what you declare as "string" is only a pointer to a null-terminated array of chars. So if you write this to a file you either only write the pointer or you get an error (depending on the compiler). If you define a fixed-length string it's a Pascal style string, i.e. an array of char (not a pointer!) with the first byte indicating the length. So... String[20] or String * 20 (?): Array of chars; first byte = length String = POINTER to array of chars; last byte = 0 Questions? *g
