Component Pascal
Component Pascal
Component Pascal is a general-purpose language in the tradition of Pascal, Modula-2, and Oberon. Its most important features are block structure, modularity, separate compilation, static typing with strong type checking (also across module boundaries), type extension with methods, dynamic loading of modules, and garbage collection. Type extension makes Component Pascal an object-oriented language. An object is a variable of an abstract data type consisting of private data (its state) and procedures that operate on this data. Abstract data types are declared as extensible records. Component Pascal covers most terms of object-oriented languages by the established vocabulary of imperative languages in order to minimize the number of notions for similar concepts. Complete type safety and the requirement of a dynamic object model make Component Pascal a component-oriented language.Starting Price: Free -

Java
Oracle
The Java™ Programming Language is a general-purpose, concurrent, strongly typed, class-based object-oriented language. It is normally compiled to the bytecode instruction set and binary format defined in the Java Virtual Machine Specification. In the Java programming language, all source code is first written in plain text files ending with the .java extension. Those source files are then compiled into .class files by the javac compiler. A .class file does not contain code that is native to your processor; it instead contains bytecodes — the machine language of the Java Virtual Machine1 (Java VM). The java launcher tool then runs your application with an instance of the Java Virtual Machine.Starting Price: Free -

C++
C++
C++ is a simple and clear language in its expressions. It is true that a piece of code written with C++ may be seen by a stranger of programming a bit more cryptic than some other languages due to the intensive use of special characters ({}[]*&!|...), but once one knows the meaning of such characters it can be even more schematic and clear than other languages that rely more on English words. Also, the simplification of the input/output interface of C++ in comparison to C and the incorporation of the standard template library in the language, makes the communication and manipulation of data in a program written in C++ as simple as in other languages, without losing the power it offers. It is a programming model that treats programming from a perspective where each component is considered an object, with its own properties and methods, replacing or complementing structured programming paradigm, where the focus was on procedures and parameters.Starting Price: Free -

Unlambda
Unlambda is a programming language. Nothing remarkable there. The originality of Unlambda is that it stands as the unexpected intersection of two marginal families of languages. Functional programming languages, of which the canonical representative is Scheme (a Lisp dialect). This means that the basic object manipulated by the language (and indeed the only one as far as Unlambda is concerned) is the function. Rather, Unlambda uses a functional approach to programming: the only form of objects it manipulates are functions. Each function takes a function as an argument and returns a function. Apart from a binary “apply” operation, Unlambda provides several built-in functions (the most important ones being the K and S combinators). User-defined functions can be created, but not saved or named, because Unlambda does not have any variables.Starting Price: Free -

Transformer Cobol
Morphis Tech
Morphis Transformer for Cobol Automated Refactoring from Mainframe to Serverless When it comes to move workloads from mainframe to the cloud, we face two possible paths: Re-hosting: a more tactical approach that preserves the original code almost untouched. Refactoring: a more strategic alternative, in which new applications, written in more modern languages, are obtained from the legacy sources. At first glance Re-hosting can be more appealing, since it represents inferior cost and risks. But if Refactoring uses very high automation, both Re-host and Refactoring approaches can be pursued in projects with similar duration, similar risks, and similar costs. We here demonstrate the Morphis Automated Refactoring, yet tailored, approach to migrate from COBOL/CICS OLTP applications to single page applications, with JavaEE or .NET server logic, fully integrated with cloud native services. Furthermore, this approach also allows us to achieve the ultimate costs. -

It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. JSON is built on two structures: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another.Starting Price: Free -

Scheme
Scheme
Scheme is a general-purpose computer programming language. It is a high-level language, supporting operations on structured data such as strings, lists, and vectors, as well as operations on more traditional data such as numbers and characters. While Scheme is often identified with symbolic applications, its rich set of data types and flexible control structures make it a truly versatile language. Scheme has been employed to write text editors, optimize compilers, operating systems, graphics packages, expert systems, numerical applications, financial analysis packages, virtual reality systems, and practically every other type of application imaginable. Scheme is a fairly simple language to learn since it is based on a handful of syntactic forms and semantic concepts and since the interactive nature of most implementations encourages experimentation. Scheme is a challenging language to understand fully.Starting Price: Free -

Assembler Code Refactoring
Rocket Software
Rocket Assembler Code Refactoring is a specialized modernization solution that automatically restructures legacy Assembler code into structured pseudocode or modern languages such as COBOL, C, or Java without altering external behavior, enabling faster, lower-risk modernization and improved maintainability. Assembler code is notoriously dense, poorly documented, and supported by a shrinking pool of specialists, making maintenance slow, costly, and error-prone; this product addresses those challenges by delivering semantics-preserving, auditable transformations that reduce outages and secure modernization without sacrificing stability. Its fully automated core engine uses mathematically guaranteed logic equivalence to eliminate conversion risk, dramatically accelerating projects while ensuring that refactored outputs are semantically identical to the original code. -

iSecurity DB-Gate
Raz-Lee Security
DB-Gate empowers IBM i customers with exciting data access capabilities, based on Open Database Connectivity (ODBC), employing standard IBM i facilities to enable fully database-transparent access to remote systems. Using native SQL on the IBM i, users can now access specific files on DB2 and non-DB2 remote databases without any special hardware appliance or software on the remote database. From interactive STRSQL and from any standard program in RPG, Cobol, C, or other languages, access is now easier and more natural than ever. DB-Gate has been proven to be a full, successful replacement for OAM, the Oracle Access Manager, which has not been supported since IBM i release 7.3. As your enterprise applications expand in database requirements and complexity, so does the need to access multiple databases from your main application server. Current methods of accessing specific files on a remote database from within the IBM i require considerable time and resources. -

XAML
Microsoft
XAML is a declarative markup language. As applied to the .NET Core programming model, XAML simplifies creating a UI for a .NET Core app. You can create visible UI elements in the declarative XAML markup, and then separate the UI definition from the run-time logic by using code-behind files that are joined to the markup through partial class definitions. XAML directly represents the instantiation of objects in a specific set of backing types defined in assemblies. This is unlike most other markup languages, which are typically an interpreted language without such a direct tie to a backing type system. XAML enables a workflow where separate parties can work on the UI and the logic of an app, using potentially different tools. When represented as text, XAML files are XML files that generally have the .xaml extension. The files can be encoded by any XML encoding, but encoding as UTF-8 is typical.Starting Price: Free -

Nix
NixOS
Nix is a tool that takes a unique approach to package management and system configuration. Learn how to make reproducible, declarative, and reliable systems. Nix builds packages in isolation from each other. This ensures that they are reproducible and don't have undeclared dependencies, so if a package works on one machine, it will also work on another. Nix makes it trivial to share development and build environments for your projects, regardless of what programming languages and tools you’re using. Nix ensures that installing or upgrading one package cannot break other packages. It allows you to roll back to previous versions and ensures that no package is in an inconsistent state during an upgrade. Nix is a purely functional package manager. This means that it treats packages like values in purely functional programming languages such as Haskell, they are built by functions that don’t have side effects, and they never change after they have been built.Starting Price: Free -

Assembly
Assembly
Assembly language is a low-level computer programming language that is used to directly control the hardware of a computer system. It consists of symbols and words that represent specific instructions to the processor. Assembly language is often used to optimize programs written in higher-level languages, as it can provide a more efficient way to access memory and other resources.
