Pattern Tab

The Pattern tab contains all of the settings used to define patterns on a selected entity. When you add a new pattern to your model, the following sections are available:


Defines the name or names of the currently defined patterns. When you add a new pattern to an entity, a default name, such as Pattern_1, is generated and default settings are applied in the Position, Properties, and Pattern use boxes. When a pattern is selected in the Name box, the cursor highlights the position of the pattern on the host screen. You can use the buttons next to the Name box to add a new pattern, delete the current one, or auto-generate patterns.

If a pattern is no longer valid (for example, the layout of the screen on the host has changed), the pattern is marked with a red X in the list after running the Entity Repair utility or setting the model to offline mode.

Auto-generating patterns simplifies the modeling process, but you may need to delete some auto-generated patterns later to enhance server performance. If you choose to have the Design Tool auto-generate patterns, you can configure properties recognition on the Pattern tab of the Preferences Setup dialog box. In addition, patterns cannot be generated automatically for a VT host.


Defines the position settings (Row, Height, Column, and Width) that describe the actual position of the pattern on the host screen. First, select a Selection mode (Linear or Rectangular).

By default, the pattern is assumed to always be located in the same place on the terminal window. If the pattern can occur in another position, use one or both of the following to describe where to look to for the pattern.

If both of these options are enabled, the expanded region is defined relative to the cursor position specified.

Definition tab

Describes the physical characteristics of the pattern and provides a view of any characters appearing on that area of the host screen. The Design Tool displays different property settings for different types of terminals. For more information, see using display attributes for patterns.

Field type and text color

For IBM 3270 and 5250 hosts, the Text check box is selected by default when a new pattern is created. To view the field type or the text color of the pattern as recognized by the host, select the Field type or Text color check boxes.

For VT and HP hosts, the Field type and Text color properties are replaced with the following:


Displays the text in the selected area. You can also select <Any text>, <Any number>, <Blank>, or < Regular Expression >. Select the Case sensitive check box if you would like the data stored in your model as case-sensitive text.

Location tab

If you have selected Search for pattern in expanded region, the settings on this tab identify the location of the pattern definition. Select the region in the terminal window using the red selection rectangle or fill in the settings for row, column, height, and width (Rectangular mode), or offset and length (Linear mode). In default color configuration, this pattern definition area is outlined in red, while the Position settings for region are outlined in green.
