Iron Spring Software

Iron Spring Software, inc. was started in 2007 with the intention of bringing the flexibility, reliability, and portability of PL/I to a wider market. Our flagship product is the Iron Spring PL/I compiler for Linux and OS/2, offering a high degree of compatibility with mainframe PL/I compilers to ease migration. Our customers span the range from individual users to an agency of a large state government. PL/I is a powerful programming language suitable for a wide range of problems. PL/I has been used to write operating systems and compilers, simulations, real-time programs, mathematical software, spreadsheets, GUI programs, and for general computing. PL/I is widely used on mainframes and midrange systems today, but since the demise of Digital Research, Inc. has not been readily available on personal computers.
