Supported Compilers

Language Environment is the prerequisite run-time environment for applications generated with the following IBM compiler products:

• z/OS XL C/C++
• OS/390 C/C++
• C for VM/ESA
• C/C++ Compiler for MVS/ESA
• AD/Cycle C/370 Compiler
• Java for z/OS
• Enterprise COBOL for z/OS
• COBOL for OS/390 & VM
• COBOL for MVS & VM (formerly COBOL/370)
• Enterprise PL/I for z/OS
• PL/I for MVS & VM (formerly AD/Cycle PL/I for MVS & VM)
• VS FORTRAN and FORTRAN IV (in compatibility mode)

In many cases, you can run compiled code generated from the previous versions of the above compilers. A set of assembler macros is also provided to allow assembler programs to run within Language Environment.
