XPEDITER is a family of mainframe testing programs by Compuware. They provide the programmer with an assortment of debugging tools for a variety of mainframe applications, including IBMCICS, TSO and IMS.
Mainframe computers or mainframes are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing. They are larger and have more processing power than some other classes of computers: minicomputers, servers, workstations, and personal computers.
Compuware Corporation is an American software company with products aimed at the information technology (IT) departments of large businesses. The company's services also include testing, development, automation, and performance management software for programs running on mainframe computer systems. The company has its headquarters in Downtown Detroit, Michigan.
Debugging is the process of finding and resolving defects or problems within a computer program that prevent correct operation of computer software or a system.

Multiple Virtual Storage, more commonly called MVS, was the most commonly used operating system on the System/370 and System/390 IBM mainframe computers. It was developed by IBM, but is unrelated to IBM's other mainframe operating systems, e.g., VSE, VM, TPF.
Computerized batch processing, since the 1964 introduction of the IBM System/360, has primarily referred to the scripted running of one or more programs, as directed by Job Control Language, with no human interaction other than, if JCL-requested, the mounting of one or more pre-determined input and/or output computer tapes.
z/OS is a 64-bit operating system for IBM mainframes, produced by IBM. It derives from and is the successor to OS/390, which in turn followed a string of MVS versions. Like OS/390, z/OS combines a number of formerly separate, related products, some of which are still optional. z/OS offers the attributes of modern operating systems but also retains much of the functionality originating in the 1960s and each subsequent decade that is still found in daily use. z/OS was first introduced in October 2000.
A debugger or debugging tool is a computer program that is used to test and debug other programs. The code to be examined might alternatively be running on an instruction set simulator (ISS), a technique that allows great power in its ability to halt when specific conditions are encountered, but which will typically be somewhat slower than executing the code directly on the appropriate processor. Some debuggers offer two modes of operation, full or partial simulation, to limit this impact.
A disassembler is a computer program that translates machine language into assembly language—the inverse operation to that of an assembler. A disassembler differs from a decompiler, which targets a high-level language rather than an assembly language. Disassembly, the output of a disassembler, is often formatted for human-readability rather than suitability for input to an assembler, making it principally a reverse-engineering tool.
Time Sharing Option (TSO) is an interactive time-sharing environment for IBM mainframe operating systems, including OS/360 MVT, OS/VS2 (SVS), MVS, OS/390, and z/OS.
Job Control Language (JCL) is a name for scripting languages used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem.
Customer Information Control System (CICS) is a family of mixed language application servers that provide online transaction management and connectivity for applications on IBM Mainframe systems under z/OS and z/VSE.
UNIX System Services (USS) is a required, included component of z/OS. USS is a certified UNIX operating system implementation optimized for mainframe architecture. It is the first UNIX 95 to not be derived from the AT&T source code. Through integration with the rest of z/OS, additional Time Sharing Option (TSO) commands are available alongside the usual UNIX services, making it possible to process UNIX files using ISPF. Extensions in JCL make it possible to use these files in batch processing.
A job scheduler is a computer application for controlling unattended background program execution of jobs. This is commonly called batch scheduling, as execution of non-interactive jobs is often called batch processing, though traditional job and batch are distinguished and contrasted; see that page for details. Other synonyms include batch system, distributed resource management system (DRMS), distributed resource manager (DRM), and, commonly today, workload automation (WLA). The data structure of jobs to run is known as the job queue.
Teleprocessing Network Simulator (TPNS)
is an IBM licensed program, first released in 1976 as a test automation tool to simulate one or many network terminal(s) to a mainframe computer system, for functional testing, regression testing, system testing, capacity management, benchmarking and stress testing. In 2002, IBM re-packaged TPNS and released
Workload Simulator for z/OS and S/390 (WSim) as a successor product.
CA-EZTEST was a CICS interactive test/debug software package distributed by Computer Associates and originally called EZTEST/CICS, produced by Capex Corporation of Phoenix, Arizona with assistance from Ken Dakin from England.
Capex Corporation was a software house based in Phoenix, Arizona founded by three former employees of General Electric. It was acquired by Computer Associates International, Inc. in 1982.
Rational Business Developer (RBD) provides a workbench for Enterprise Generation Language (EGL) development, an end-to-end rapid development approach.
Program animation or Stepping refers to the now very common debugging method of executing code one "line" at a time. The programmer may examine the state of the program, machine, and related data before and after execution of a particular line of code. This allows evaluation of the effects of that statement or instruction in isolation and thereby gain insight into the behavior of the executing program. Nearly all modern IDEs and debuggers support this mode of execution. Some testing tools allow programs to be executed step-by-step optionally at either source code level or machine code level depending upon the availability of data collected at compile time.

JEM, the BEE is a Java, cloud-aware application which implements a Batch Execution Environment, to help and manage the execution of jobs, described by a Job Control Language (JCL). JEM, the BEE performs the following functions:
OpenFrame is a mainframe rehosting solution developed by TmaxSoft that aims to help customers move existing mainframe assets to the cloud quickly and with minimal risk. It replaces legacy CICS/IMS/JES mainframe engines and shifts business applications written in legacy code like COBOL and PL/I to Linux. This allows reduced licensing costs compared to the mainframe.
