Executable File Header Utility (EXEHDR)

The Executable File Header Utility (EXEHDR) displays and modifies the contents of an executable-file header. EXEHDR generates an Output listing showing the contents of the file header and information about each object or segment in the file. Options are provided that let you change values in the file header.

Uses of EXEHDR include:

• Determining whether a file is an application or a dynamic link library
  
• Viewing and changing the attributes set by the module definition file
  
• Viewing the number and size of code and data segments.

You can use EXEHDR with DOS or OS/2 applications and dynamic-link libraries.
