BLIS/COBOL

Bliss/COBOL are two different computer programming languages. Computer programming languages are used to write instructions that tell a computer what to do. Blis is the language most often used to write the instructions for computer networks, while COBOL is the language used for managing business data, like customer records and accounts. Both of these languages are very old, and most modern computer programs are written in more modern programming languages like Python and Java.
