+.SH NAME
+Tcl_RecordAndEval \- save command on history list before evaluating
+.SH SYNOPSIS
+.nf
+\fB#include <tcl.h>\fR
+.sp
+int
+\fBTcl_RecordAndEval\fR(\fIinterp, cmd, flags\fR)
+.SH ARGUMENTS
+.AS Tcl_Interp *interp;
+.AP Tcl_Interp *interp in
+Tcl interpreter in which to evaluate command.
+.AP char *cmd in
+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_RecordAndEval\fR is invoked to record a command as an event
+on the history list and then execute it using \fBTcl_Eval\fR
+(or \fBTcl_GlobalEval\fR if the TCL_EVAL_GLOBAL bit is set in \fIflags\fR).
+It returns a completion code such as TCL_OK just like \fBTcl_Eval\fR
+and it leaves information in \fIinterp->result\fR.
+If you don't want the command recorded on the history list then
+you should invoke \fBTcl_Eval\fR instead of \fBTcl_RecordAndEval\fR.
+Normally \fBTcl_RecordAndEval\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.
+.PP
+Note that \fBTcl_RecordAndEval\fR has been largely replaced by the
+object-based procedure \fBTcl_RecordAndEvalObj\fR.
+That object-based procedure records and optionally executes
+a command held in a Tcl object instead of a string.
