Screen colors and attributes are defined in a color mapping file. A sample is provided for you to tailor; see Sample configuration and mapping files for details. It is recommended that you create your own customized mapping file.
export CICSCOL=⁄var⁄cicscli⁄mycols.ini
If you do not specify otherwise, a file name of cicscol.ini in the <install_path>⁄bin subdirectory is assumed.
A color mapping file provides alternative representations in hardware environments where it is not possible exactly to replicate 3270 screen attributes, for example, blinking or underscore. The color mapping file therefore defines how 3270 screen attributes are emulated on the client hardware.
If the color mapping file specifies a mapping for an attribute, this mapping is used even if the hardware upon which the CICS® Universal Client is running actually supports the screen attribute.
If an application requests a 3270 field to be displayed with, for example, underscore, and no emulation setting has been specified, and the hardware cannot display underscore, the field is displayed without any highlighting at all.
The color mapping file is optional. However, for most hardware environments a mapping file is required if blinking or underscore support is required by the emulator.
You can change the color mapping file at any time, although changes do not take effect until the next time the terminal emulator is started.
