Binary Indicates the entry is a raw, numeric value.
Hex Indicates hexadecimal notation. This is used with both ASCII characters (0 – 9, A – F) and numeric values.
BCD Indicates the entry is a numeric value where each four bits represents a decimal digit.
FPn Indicates the entry is the ASCII representation of a floating-point number with n places following the
decimal point.
<n> Indicates a single 8-bit byte. When the contents are numeric, it indicates a hexadecimal numeric value; i.e.
<84> represents hexadecimal 84 (132 decimal). When the contents are capital letters, it represents a
