## Detailed Description

Represent general characteristics of a byte in the program.

Each byte of the program may be in one of four states.

- unexplored
- start of instruction
- start of data
- second, third (tail) byte of instruction or data.

Initially, all bytes of the program are unexplored. IDA modifies flags and doing so converts bytes to instructions and data.
