IBM's High Level Assembler (HLASM) is a low level programming language for z/Architecture mainframe computers. Many legacy codebases contain large subsets written in HLASM for various reasons, and such components usually had to be manually rewritten in COBOL or PL/I before a migration to a modern framework could take place. Now, the Raincode ASM370 compiler for .NET supports HLASM syntax and emulates the data types and behaviour of the original language, allowing one to port, maintain and interactively debug legacy mainframe assembler code under .NET.
