What is an EQL file?
An EQL file is a settings file used by MathType, an application for creating mathematical notation. It contains configuration information for a MathType object, such as a toolbar, menu, or another interface element, the user can modify to customize their appearance and behavior.
More Information
Most MathType users will not encounter EQL files since they are stored in the application's installation directory, and the program references them. However, some users may discover them when migrating preferences between MathType installations.
NOTE: EQL files' filenames relate to the object for which they store settings (e.g., Toolbar.eql defines the layout and functionality of MathType's toolbar). Also, if an EQL file becomes corrupt, users can delete it to restore the default setting since the software automatically regenerates the necessary configuration file.
How to open an EQL file
You should not attempt to open EQL files. Instead, Design Science MathType references the files in the app's installation directory.

An EQL file may also be a source code file that contains embedded SQL (EQL) commands, which are used within a "host" program (likely written in the C programming language). Software developers use a preprocessor to parse the embedded SQL commands in the EQL file and convert them to calls in the host program's language to be uniform. Then, developers compile the source code into machine language with a compiler that an end user runs on a computer as a program.
More Information
Software developers use EQL to include SQL queries directly within a program's source code. SQL queries included in EQL files can perform tasks such as retrieving, updating, or managing database records. The process is beneficial for developing applications that require direct database integration, such as enterprise applications, because the SQL queries streamline database communication.
How to open an EQL file
You can open EQL files with any source code or text editor, such as Microsoft Visual Studio Code, Microsoft Notepad, or Apple TextEdit. However, text editors do not come with features included with source code editors, such as syntax highlighting, that make it easier for developers to code.
