Administrator
A Revolve user who has been given the rights to configure projects as single user or shared and to authorize any additions or deletions of data that may be necessary. Refer to Chapter 4 "Using Revolve," section Modes of Operation for a list of Administrative rights.
Active project
The active project is the project that is open and currently being used. Only one project can be active at a time.
Annotation path
The annotation path specifies which directories Revolve will write and read user applied annotations. The default directory is \revolve\redb.

C

Code Flow view
The Code Flow view provides a flow chart of the calling hierarchy of the paragraphs and sections in a COBOL program. It can also depict fall throughs and dynamic branching.
Complete Project dialog box
The Complete Project dialog allows the user to fill in gaps in a project due to missing programs, copybooks, etc. This is a process which should precede any system wide analysis.
Component
A component is a single source file. When loaded into a project, it has a type which can include BMS, COBOL, DBD, MFS, PSB, or JCL. Copybooks, includes, procs, and control-cards are not considered components.

D

Data Impact
The effect, or impact, that a data modification will have on the integrity of the system. For example, the variable "A" needs to be enlarged; however, in another area of the source code "A" interacts with "B." The user should consider the data impact when making the modification and determine if "B" should also be enlarged.
Data Definition Language (DDL)
Defines DMS 1100 schemas by specifying names and attributes of areas, sets, records, and data names stored in a DMS database. DDL consists of basic clauses and combinations of clauses used by the DDL processor to create schemas.
Data Management Communications Area (DMCA)
Program buffer through which DMR passes information to the user program.
Data Management Routine (DMR)
On-line routine that access and updates the database.
Data Management System (DMS)

Dongle
See Usage counter.

E

Execution Simulator
The Execution Simulator provides a mechanism for analyzing the control flow in a system. Revolve traces the path through programs and screens.
Executive Control Language (ECL)
A Unisys language used for constructing jobs that compile or run programs on 1100 series systems.
Extension
An extension is the DOS file type used for copybooks, includes, and proclibs. The default extensions include ".lib", ".cop", ".cpy", and ".cbl".

I

Impact
Impacts occur when source code elements are modified and that change effects other source code elements in the system.
Information Browsers
A group of dialog boxes used to present information about various types of elements and relationships in the system.
Integrated Editor
An editing tool that supplies the user with direct and unlimited access to source code. Changes to source code can be implemented singularly or across an entire application. Also appears in encapsulated form as the Split Screen Editor
Inventory view
The Inventory view provides a graphical view of COBOL and JCL components. The COBOL inventory shows the main program, copybooks, include files, and databases. The JCL/ECL inventory represents the job/run, steps, devices/files, executables, and dds.

L

Live fall-through
A fall through to a label that can be performed somewhere in a program. For example, if a program has a statement "PERFORM INIT." then any fall through past the "INIT" label would count as one live fall through.

M

Match
The Match button is located on the edit bars in most of Revolve's interfaces. Always preceded by an edit field and sometimes by a type drop-down listbox. Allows for search criteria to be specified.
Metering
In some Revolve-based products, someone needs to meter your application code before you can process that code using the Revolve-based product. Only one person needs to meter the code and it is then available for everyone to process. To meter code, you need write access to the metering control file and you need an enabled usage counter.
Metrics tool
The Metrics tool features methods for calculating several statistical measures of complexity.

N

New Programming Environment (NPE)
Integrated facility that compiles language programs such as COBOL and FORTRAN. NPE has separate front-end language compilers, but uses a common code generator, linking system, run-time system, and programmer advanced debugging system (PADS) for all languages. Formally known as the Universal Compiling System (UCS).
NPE COBOL
Formally known as UCOB, the term now used is NPE COBOL. This is an implementation of ANSI-85 COBOL with Unisys extensions.

O

Options
Options appear in some browsers and tools and allow the Revolve user to adjust the way information is displayed. Normally accessible from the Options button, located on the button bar. There are also Options available from the Utilities menu, specific to users and administrators.

P

Power key
The F1 through F12 function keys can be assigned user-defined queries.
Project
A project contains the parsed representation of all the components that have been loaded. It is contained in a file with the extension ".prj".
Project Manager window
The Project Manager window is the control panel for the active project. It is used to view and manipulate the components of a project.
Project path
The project path specifies which directories contain the component databases. The default directory is \revolve\redb, but component databases can exist in other directories or on other machines.

R

Regular Expression
A language for specifying patterns that match a sequence of characters. Regular expressions consist of normal characters which match the same character in the input, character classes which match any single character in the class, and other characters which specify the way that parts of the expression are to be matched against the input.
Relational Data Management System (RDMS)
Unisys relational data management system. A software product that manages relations as a component of the Universal Data System (UDS).
Report
A text based document created by a script
REQL
Revolve Query Language: database language specifically designed to answer questions about source code.

S

Schema
The plan or definition for the logical structure of a Unisys database.
Screen view
The Screen view provides an image of a BMS or MFS screen as it would appear on a terminal.
Script
Scripts are programs that automate activities in Revolve. There are many scripts provided with the product.
Search Directory
A Search Directory is a directory on the local system that is identified as containing files of a certain type. The Automatic Component Locator uses search directories to locate and load files.
Security key
See Usage counter.
Selected Element
A description of the selected element appears at the bottom of the desktop. An element is selected by right clicking on the element in any tool or browser and choosing Select.
Set
Hierarchical collection of record types in a database.
Source path
The source path specifies which directories contain copybooks, includes, and proclibs. It needs to be set so that these files can be found and included during parsing.
Source view
Provides a display of the source code. The Source view shows a logical view of the source files, including COBOL and JCL, with copybooks and include files interleaved.
Speed Menu
The pop-up menu for the selected item. This menu appears when you right-clicks the mouse button on the selected item.
Split Screen Editor
The encapsulated version of the Integrated Editor that appears when the View Source Code button is pressed. Allows access to source code for editing.
Status bar
The status bar is located at the bottom of the desktop window and at the bottom of some Revolve interfaces. It contains several objects which provide quick access to important information and functions. The right hand side of the status bar provides a display of the selected element.
Subproject
A subproject is a collection of individually specified items that are taken from a Revolve project to be analyzed and modified in specific ways.
Subschema
Identifies a subset of areas, sets, records, and data names defined in the database schema available to user sessions.
Subschema Data Definition Language (SDDL)
Language that describes the DMS database to application programs. Consists of clauses and combinations of clauses used by the SDDL processor to create subschemas. Translates a source subschema into a set of interpretative tables and a series of records to be included by the DML program.
System view
Depicts the calling relationships between all JCL jobs, programs, screens, and databases in the project.

T

Type
The class of an element. For example, cobol_state_move is the type for COBOL move statements, and cobol_label_para is the type for paragraphs.

U

UCOB
UCS COBOL, also known as, NPE COBOL. This is an implementation of ANSI X3.23-1985.
Usage counter
A usage counter, also known as a dongle or security key, resembles the plug by which a printer is plugged into a computer.
You receive a usage counter with the Metering Administration pack. If you (or your systems administrator) have not already ordered one of these packs, and you need to meter code, please contact your MERANT sales representative.
In some Revolve-based products, the code is metered by means of the usage counter, which is credited with a number of lines of code. When someone meters code, the usage counter must be attached to the back of that person's PC and then the counter is debited by the appropriate number of lines.
See also metering.
Users
Individuals with access to analysis tasks and no administrative rights.

W

Wildcard
The Revolve wildcard character is an asterisk (*). It appears by default in most Match edit boxes. It establishes similar strings in Match searches.
Worksheet
Holds the points of interest that you identify when analyzing your application. The worksheet keeps track of what's of interest and the decisions made. You can record details on each point of interest, such as the reasons for it being of interest, what sort of problem it represents, and what further treatment it needs if any.
