 '\"	needed;  use .AS below instead)
 '\"
 '\" .AS ?type? ?name?

 .SH NAME
 Tcl_RecordAndEvalObj \- save command on history list before evaluating
 .SH SYNOPSIS
 .nf
 \fB#include <tcl.h>\fR
 .sp
 int
 \fBTcl_RecordAndEvalObj\fR(\fIinterp, cmdPtr, flags\fR)
 .SH ARGUMENTS
 .AS Tcl_Interp *interp;
 .AP Tcl_Interp *interp in
 Tcl interpreter in which to evaluate command.
 .AP Tcl_Obj *cmdPtr in
 Points to a Tcl object containing a command (or sequence of commands)
 to execute.
 .AP int flags in
 An OR'ed combination of flag bits.  TCL_NO_EVAL means record the
 command but don't evaluate it.  TCL_EVAL_GLOBAL means evaluate
 the command at global level instead of the current stack level.
 .BE

 .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_EvalObjEx\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_EvalObjEx\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_EvalObjEx\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.
