One computer programming
language was designed specifically for business, Common Business-Oriented
Language, COBOL. COBOL has been transforming and supporting business globally
since its invention in 1959. COBOL is responsible for the efficient, reliable,
secure and unseen day-to-day operation of the world’s economy. This PDF covers
the following topics related to COBOL :Getting started, Why COBOL, VSCode
with Zowe Explorer, VSCode with Z Open Editor, VS Code with Code4z Open-Source
