//--------------------------------------
//--- 010 Editor v2.0.2 Binary Template
//
// Author: Peter Kankowski http://smallcode.weblogs.us
// File mask: *.exe,*.dll,*.scr,*.8b?,*.drv,*.ocx
// Purpose: to display executable file headers.
// Supports DLLs, Windows CE and Win64 executables.
// Displays informative names for all flags and fields.
// Update: Didier Stevens https://DidierStevens.com
// 2010/09/05: Added DYNAMIC_BASE, FORCE_INTEGRITY, NX_COMPAT and NO_ISOLATION to DLLCHARACTERISTICS struct
//--------------------------------------
