COBOL 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 a output file which is known as load module. This output file contains executable code in the form of 0s and 1s.
