An 88 level-number declares a condition name (a so-called 88-level) which is true when its parent data item contains one of the values specified in its VALUE clause. [142] For example, the following code defines two 88-level condition-name items that are true or false depending on the current character data value of the wage-type data item.
In fixed format code, line indentation is significant. Columns 1–6 and columns from 73 onwards are ignored. If a * or / is in column 7, then that line is a comment. Until COBOL 2002, if a D or d was in column 7, it would define a "debugging line" which would be ignored unless the compiler was instructed to compile it. Cobra
The hyphen is used by nearly all programmers writing COBOL (1959), Forth (1970), and Lisp (1958); it is also common in Unix for commands and packages, and is used in CSS. [5] This convention has no standard name, though it may be referred to as lisp-case or COBOL-CASE (compare Pascal case), kebab-case, brochette-case, or other variants.
Generally, var, var, or var is how variable names or other non-literal values to be interpreted by the reader are represented. The rest is literal code. Guillemets (« and ») enclose optional sections.

In the COBOL programming language, a user-defined function is an entity that is defined by the user by specifying a FUNCTION-ID paragraph. A user-defined function must return a value by specifying the RETURNING phrase of the procedure division header and they are invoked using the function-identifier syntax.
Columns 1, 2, and 3 of a JCL comment statement contain //* Name-Field: The name field identifies a particular statement so that other statements and the system can refer to it. For JCL statements, it should be coded as follows: The name must begin in column 3. The name is 1 through 8 alphanumeric or national ($, #, @) characters.
PHP has hundreds of base functions and thousands more from extensions. Prior to PHP version 5.3.0, functions are not first-class functions and can only be referenced by their name, whereas PHP 5.3.0 introduces closures. [35] User-defined functions can be created at any time and without being prototyped. [35]
