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

Many atomic data types supported: char, wchar, byte, ubyte, word, uword, long, ulong,longlong, half float, float, double, OLE Date/Time, DOSTIME, DOSDATE, FILETIME, time_t,and time64_t
Conditional structure elements (if and switch)
Big Endian or Little Endian rendering
Add floating structures that re-renders on caret position changes
Add locked structures which stick to a document and offset
Verify expected byte sequences in a document against the structure definition's expectedvalues
Integrated Functions enable automatic file format parsing and data manipulation

Use either a Simple or Resynchronizing binary compare
Resynchronizing Compare color codes the differences

Set comparison length independently for source and target files

Includes 3 palettes and the ability to use user-defined palettes (Microsoft .PAL file format)
Zoom visualizer width and height independently
Automatic scaling to match editor view
Displays editor selection
Allows selection of data within the editor

Modify your data in-place using embedded operations
Operations can be applied to a selection or an entire document
Operations include: set floor value, set ceiling value, lower case, upper case, swap case, byte flip, block shift, ~, <<, >>, ~, |, &, +/-, +, -, *, /, %
