  - Interactive Usage
  - OML, Tcl, Python, and R Scripts.
    Compose supports OML, Tcl, Python, and R languages. The use of the interpreter language is first defined by the script being executed.
  - Macros
    You can record your session actions (in the Editor) as macros to replay them at a later time using the Macros menu.
- Run Scripts
  Click Run to execute a script.
- Profile Scripts
  Run files and profile them at the same time.
- Create Plots
  In Compose, you can create 2-D and 3-D plots using OML plotting commands.
- Edit Properties of Plots
  In Compose, you can edit the properties of plots created with OML plotting commands.
- Debug Code
  Use the Debugger to find errors in the script.
- Compose Notebook
  The Compose Notebook is a web-based implementation of Compose’s OpenMatrix Language (OML) into a Jupyter Notebook. Notebooks (see www.jupyter.org) are a powerful way to execute and demonstrate scripted languages.
- Graphical User Interfaces
  Learn about the methods, functions and file input and output options for creating a GUI.
- CAE Applications
- HDF5 Viewer
  Use the HDF5 Viewer to import data and navigate through the hierarchy of .hdf5 files.
- MAT Explorer
  Use the MAT Explorer interface to explore and load variables from one or more .MAT files, providing a visual way to see the contents of selected .MAT files and to import variables into an OML session.
- Signal Viewer
  Use the Signal Viewer to import and treat (basic) signals in both time and frequency domains, as well as generate signals based on the most common waveforms such as step, chirp and sawtooth.
- Plot Assistant
  Use the Plot Assistant to create plots from the various 2D and 3D OML plot types.
- Extension Manager
  Use the Extension Manager to create custom extensions, load extensions automatically, and add custom documentation for defined features.
- OML Functions in HyperWorks Products
  OML functions can be registered from the Compose graphical user interface or via a preference file and later opened in certain HyperWorks products.
- OML Libraries
  Additional libraries can be written in the C/C++ or Fortran language and interfaced with OML.
Reference Guides
Reference guides are available for functions and commands supported by OML, Tcl, and Python.
