You can associate a file extension with the content type of a COBOL file, using
Window > Preferences > General > Content Types.
The IDE currently provides support for the following COBOL content types:
- COBOL Source File - this file is syntax colorized when it is loaded into the COBOL editor, optionally background parsed,
and compiled using the COBOL compiler. The default extensions are
.cbl and
.cob.
- COBOL Copybook - this file is syntax colorized when it is loaded into the COBOL editor, and is optionally background parsed.
The default extensions are
.cbl and
.cpy.
