See lessThe function(s) performed by the paging software is (are)
Paging works by writing data to, and reading it from, secondary storage for use in primary storage. Paging is a basic function in memory management for a computer's operating system (OS) as well -- this includes Windows, Unix, Linux and macOSs.

In analyzing the compilation of PL/I program, the term "Syntax analysis" is associated with
The syntax analysis phase then checks whether the token sequence conforms to the grammar rules of the PL/I language. If any syntax errors are found, the compiler will generate error messages.

If a special forms are needed for printing the output, the programmer specifies these through JCL.
JCL is used in a mainframe environment to act as a communication between a program (Example: COBOL, Assembler) and the operating system. In a mainframe environment, programs can be executed in batch and online mode. Example of a batch system can be processing the bank transactions through a VSAM (Virtual Storage Access Method) file and applying it to the corresponding accounts.
Batch and online processing differ in the aspect of input, output and program execution request. In batch processing, these aspects are fed into a JCL which is in turn received by the Operating System.
A job is a unit of work which can be made up of many job steps. Each job step is specified in a Job Control Language (JCL) through a set of Job Control Statements.
