runtime settings
Log, trace, and problem determination settings defined in the file that are deployed to the runtime environment.
screen capture
An XML representation of a host screen, stored in a .hsc file, used to create or customize a screen customization, screen combination, transformation, global rule, or macro. Screen captures are useful because they enable you to develop a ZIETrans project even when not connected to the host. They are also useful in creating macros which are the core of ZIETrans Integration Object and Web services support.

Screen captures of video terminal (VT) host screens can be used to create or customize a macro using the Visual Macro Editor and as the check-in screen when configuring pooling. They cannot be used to create screen customizations, screen combinations, transformations, default rendering, or global rules.

screen combination
A type of ZIETrans screen event designed to gather output data from consecutive, similar host screens, combine it, and display it in a single output page. The screen combination definition, stored in a .evnt file, includes a set of screen recognition criteria for both the beginning and ending screens to be combined, how to navigate from screen to screen, and the component and widget to use to recognize and render the data gathered from each screen.
screen customization
A type of screen event designed to perform a set of actions when a host screen is recognized. A screen customization definition, stored in a .evnt file, includes a set of criteria for matching host screens, and actions to be taken when a host screen matches these criteria.
screen event
A ZIETrans event that is triggered when a host screen is recognized by matching specific screen recognition criteria. There are two types of screen events, screen customizations and screen combinations.
screen recognition criteria
A set of criteria that ZIETrans uses to match one or more screens. When a host displays a screen, ZIETrans searches to determine whether the current host screen matches any of the screen recognition criteria defined for any screen event in your project. If ZIETrans finds a match, the defined actions for the screen event are performed.

Screen recognition criteria are also used in the process of recording a macro; in this context they are sometimes called descriptors.
