02offset

02Offset is a term used in digital data formats and software to denote a value that indicates the location of a block of data relative to a defined base. The prefix “02” commonly reflects a two-byte (16-bit) offset field in certain file format specifications, though the exact size can vary by implementation. In general, a 02Offset is an unsigned integer describing how many bytes separate the base reference from the start of the target segment.

In practice, 02Offset appears in binary headers where it marks the position of metadata, image tiles, audio chunks, or other data blocks. Parsers or loaders read the 02Offset field and convert the raw byte sequence into a usable address, applying endianness rules to interpret the value correctly. Some specifications distinguish 02Offset from larger or differently sized offset fields (such as 04Offset or 08Offset), indicating the length of the stored offset rather than its meaning.

In programming and data processing, 02Offset is often manipulated during loading, relocation, or concatenation of data blocks. Adjustments may be required when blocks are shifted, memory is reallocated, or alignment constraints are applied. Debugging and reverse engineering contexts may use 02Offset to map logical data structures to their physical locations within a file or memory image.

Examples of use are found in custom or semi-formal file formats where a header reserves a 02Offset for the starting position of a particular data section. While not a universally standardized term, 02Offset serves as a concise label for a two-byte pointer-like value used to locate data blocks. See also: offset, base address, pointer, endianness.
