READ Variable [ , Length ]
Reads the standard output as binary data whose type is given by the type of the variable. The binary representation is the one used by the WRITE instruction.
If Variable is a string, you can specify a length that indicates the number of bytes to read. If no length is specified for a string, it is is read from the stream.
READ # File , Variable [ , Length ]
Same as above, except that the data are read from the stream File.
