COBOL is widely used in the banking and finance industry for its reliability and security features. A tutorial on sending text messages using COBOL has been provided, which requires a Vonage API account, a virtual phone number, and a COBOL compiler such as GnuCOBOL. The tutorial covers the basics of COBOL programming, including data structures and module structure. It also explains how to define variables, use filler keywords, and call external programs using the SYSTEM program. The completed program is provided, which sends a text message using the Nexmo CLI. The tutorial concludes with suggestions for further exploration and resources for learning more about COBOL.
