The IOA environment uses extended color support if the terminal is capable of supporting it. Various defaults are set so that if no changes are made, extended color is used wherever possible.
Two VTAM commands can be used to help determine whether a particular terminal supports color:
Table 29 VTAM Commands for Determining Color Support
Command |
Description |
|---|---|
RPQ |
When this VTAM command is issued to a terminal, the terminal responds with an indication whether it supports extended color. |
Note: RPQ is a physical command, which is not supported by some older control units. |
|
LOGMODE |
LOGMODE is an entry in a VTAM table that logically defines the capabilities of a terminal. The following table indicates whether the capability of the terminal to support extended color is determined by the contents of the VTAM LOGMODE entry: |

In this table, TCOLOR and ICOLOR are IOA Profile variables. For more information about these variables, see IOA Profiles.
For TSO/ROSCOE Cross‑Memory and CICS, the appropriate change must be applied before the ICOLOR variable is activated.
