Each logical record starts with a byte containing the value 77. This is the ASCII code for the letter "M", which, in turn, stands for multitype. So far, this is the only type of record stored in the file; however, it is possible, in the future, to add more types such as pictures, sounds, additional parse information, and other files.
Following the first byte, there is a two byte unsigned integer that contains the total number of entries in the record. The number is stored in Little Endian format, which means the least significant byte is stored first. This is the format used on the Intel family of processors and is the standard used by most file formats. Also, please note, this value is not the number of bytes to follow, but instead the number of different data types are stored. You should implement a simple "for-loop" to read the entries from the file.
Each multitype row can contain any assortment of Boolean, Byte, Empty, Integer, and String entries. In future implementations of this file format, more entry types can be created.
