WRITE Expression [ , Length ]
Writes expressions to the standard output using their binary representation.
If Expression is a string, you can specify a length that indicates the number of bytes to write. If no length is specified for a string, it is directly written to the stream just before the string data.
WRITE # File , Expression [ , Length ]
Same as above, except that the expressions are sent to the stream File.
