PARM is an abbreviation that stands for "parameter." A parameter is a value or attribute that defines the characteristics or behavior of a system, program, or process. It is a variable element used in the design and execution of various procedures.
In the context of computer programming, a PARM is often used to refer to a specific value that is passed to a program or function to modify its behavior or define its execution. These values can be provided by the user or set by default within the program itself. Parameters play a crucial role in controlling the flow and functionality of a program, as they allow for customization and flexibility in its operation.
Parameters can take various forms, such as numeric values, strings, or even more complex data structures. They can be used to define limits, thresholds, input requirements, or any other specifications necessary for the program's execution.
The term PARM is commonly used in mainframe computing environments, where it is often associated with job control language (JCL) and control statements. Within JCL, PARM is typically used to pass information or directives to programs or to specify particular options or configurations.
Overall, a PARM is a parameter or variable that is used to define and influence the behavior or characteristics of a system, program, or process, allowing for customization and flexibility in its execution.
