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. When the data item contains a value of 'H', the condition-name wage-is-hourly is true, whereas when it contains a value of 'S' or 'Y', the condition-name wage-is-yearly is ...
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.
Use of IBM COBOL was so widespread that Capex Corporation, an independent software vendor, made a post-code generation phase object code optimizer for it. [3] The Capex Optimizer became a quite successful product. [4] Although the IBM COBOL Compiler Family web site [5] only mentions AIX, Linux, and z/OS, IBM still offers COBOL on z/VM and z/VSE.
They are used to encode simple range comparisons on a single data field. So I could define condition names PAY-IS-SALARY and PAY-IS-HOURLY on the 1-character data field SALARY-TYPE as tests for the values 'S' and 'H', for example. Then the statement "IF PAY-IS-SALARY" is equivalent to "IF SALARY-TYPE = 'S'". Comparison ranges can also be coded.

The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem. [1] The purpose of JCL is to say which programs to run, using which files or devices [2] for input or output, and at times to also indicate under what conditions to skip a step.
