Geoworks object code file
File type: Various data file
An EOBJ file is an object code file used by Geoworks development software.
It contains compiled code intended for use in a Geoworks GEOS application and is not normally a user-openable document.

The EOBJ file extension is associated with Geoworks, the developer of the GEOS operating system and Geoworks Ensemble software. An EOBJ file stores compiled object code produced during application development.
The file is an intermediate part of the development process. It is used with other project files and development tools before the code is linked into a GEOS application or other runnable software.
EOBJ files belong to the legacy Geoworks development environment for DOS-compatible systems and are no longer in common use.
An EOBJ file is intended for the original Geoworks development tools rather than for a general-purpose file viewer. Use the compatible Geoworks GEOS development environment on a DOS-compatible system if the file needs to be inspected or used in a project.
Geoworks Ensemble or another GEOS runtime does not normally open EOBJ files as documents; the file is generally supplied to the development toolchain for linking.
An EOBJ file cannot usually be converted meaningfully into a document or a commonly used executable format. It is compiled object code rather than a source or data file.
To create usable GEOS software, the file must normally be processed by the original Geoworks development toolchain and linked with the rest of the project. Rebuilding from the original source code is the practical alternative when that toolchain is unavailable.
