View and edit data rendered as natural data type (byte, word, float, string, Unicode string, time_t, time64_t, structure reference, etc.)
Integrated with Structure Viewer
Array support (add multiple bookmarks with single definition)
Calculations supported for address, length, and count (array) definitions: +, -, *, /, %
Functions supported for address, length, and count (array) definitions: UByteAt(), UShortAt(), ULongAt()
Constants supported for address, length, and count (array) definitions: last (bookmark), start (first bookmark), arrayindex, filelength

View and edit data in its natural structure and form
File format resembles C/C++ style structure definition
Embedded, nested and reference other structures in your definitions
Many atomic data types supported: char, wchar, byte, ubyte, word, uword, long, ulong, longlong, float, double, OLE Date/Time, DOSTIME, DOSDATE, FILETIME, time_t, and time64_t
