The .gcl file extension is associated with GNU Common Lisp, a GNU implementation and development environment for the Common Lisp programming language.
A .gcl file stores data used by the GNU Common Lisp tool. Its contents and purpose depend on the part of the GCL environment that created or uses the file.
Open the file with GNU Common Lisp on a system where GCL is installed. Because the file may contain implementation data rather than standalone source code, it should normally be used from within the GCL environment.
