.SH DESCRIPTION
.PP
\fBTcl_RecordAndEvalObj\fR is invoked to record a command as an event
on the history list and then execute it using \fBTcl_EvalObj\fR
(or \fBTcl_GlobalEvalObj\fR if the TCL_EVAL_GLOBAL bit is set
in \fIflags\fR).
It returns a completion code such as TCL_OK just like \fBTcl_EvalObj\fR,
as well as a result object containing additional information
(a result value or error message)
that can be retrieved using \fBTcl_GetObjResult\fR.
If you don't want the command recorded on the history list then
you should invoke \fBTcl_EvalObj\fR instead of \fBTcl_RecordAndEvalObj\fR.
Normally \fBTcl_RecordAndEvalObj\fR is only called with top-level
commands typed by the user, since the purpose of history is to
allow the user to re-issue recently-invoked commands.
If the \fIflags\fR argument contains the TCL_NO_EVAL bit then
the command is recorded without being evaluated.
