This is a repackaged software that includes the charges of installation and configuration of COBOL, which is a high-level language. One must understand the way COBOL works. Computers only understand machine code, a binary stream of 0s and 1s. COBOL code must be converted into machine code using a compiler. Run the program source through a compiler. The compiler first checks for any syntax errors and then converts it into machine language. The compiler creates an output file which is known as a load module. This output file contains executable code in the form of 0s and 1s.
