Understand is a cross-platform, multi-language, maintenance-oriented IDE (interactive development environment). It is designed to help maintain and understand large amounts of legacy or newly-created source code. The source code analyzed may include Ada, C++, C#, FORTRAN, Java, JOVIAL, and/or Delphi/Pascal.

It offers code navigation using a detailed cross-reference, a syntax-colorizing “smart” editor, and a variety of graphical reverse engineering views.
Understand creates a repository of the relations and structures contained within the software project. The repository is then used to learn about the source code.

Supported Languages
The following list provides a brief overview of the language versions and/or compilers supported:
Ada: Understand supports Ada83, Ada95, and Ada05 code, separately, or in combination.

C/C++: Understand analyzes K&R or ANSI C source code and most constructs of the C++ language. Understand works with any C compiler, and has been tested with most of the popular ones. Note that C++ templates are not yet supported.

C#: Understand supports C#.

FORTRAN: Understand supports FORTRAN 77, FORTRAN 90, FORTRAN 95, and FORTRAN 2003 in both free and fixed format. Extensions supported include Harris FORTRAN and DEC FORTRAN. We often expand Understand to support common compiler extensions. If you find that the compiler extensions you are using are not currently supported, contact us at support@scitools.com.

Java: Understand supports most of JDK 1.3, 1.4, 5, and 6. Specifically, the generics introduced in JDK 5 are not currently supported. Source code containing generics may be analyzed but generics information will be ignored.

JOVIAL: JOVIAL73 and JOVIAL3 are supported.

Pascal: Understand supports all versions of Borland's Delphi language and Borland's Turbo Pascal language. It also supports ISO 7185: 1990 (also known as Unextended Pascal) with DEC Pascal extensions. You can also enable support for Ingres embedded SQL statements.

PL/M: The standard version for PL/M 80/86 is supported.

VHDL: We aim to support VHDL-87, VHDL-93, and VHDL-2001.

Web Languages: Understand supports PHP, HTML, CSS, and jаvascript.
