Regular Expressions
The COBOL Programming Language has fallen out of favor, but, for a long time, it was the language used for business applications. COBOL has a very interesting identifier format. COBOL identifiers must start with a letter and then can be followed by a series of letters, numbers or dashes (minus sign). There is one restriction: dashes cannot appear next to each other.
