No you haven't; there is no color in e-mail.

A component called the TIOC[1] or VTIOC[2] handles the interface to
the communications access method. It is responsible for signalling the
completion of, e.g., TGET, TPUT, to the TSO user's address space. The
[V]TIOC uses the same cross-memory mechanisms as amy other activity
that could cause an address space to become ready.

CICS runs multiple users in a single Application Owning Region (AOR);
TSO has no equivalent. When there are multiple CICS address spaces,
CICS uses, e.g., VTAM, to communicate among them.
[1] Obsolete; was used for TCAM.
[2] Used for VTAM
