Common Business-Oriented Language (COBOL) is a programming
language similar to English that is widely used to develop business-oriented
applications in the area of commercial data processing. COBOL has been almost a
generic term for computer programming in this kind of computer language.
However, as used in this chapter, COBOL refers to the product IBM Enterprise
COBOL for z/OS and OS/390®.
To run COBOL programs in the UNIX environment, you must
compile them with the Enterprise COBOL or the COBOL for OS/390 and VM compiler.
They must be reentrant, so use the compiler and binder option RENT.
