Detailed Description

byte-level data characteristics of stored data.

Used for the interpretation (read or write) of data in buffers that are read directly from disk into buffer. In that case cross-platform issues arise: byte-ordering and int/float layout. The IBM Format is only supported for the types that are used in SEG-Y sample data handling. SGI is a future option.
