NAME

SYNOPSIS
#include <tcl.h>
int
Tcl_RecordAndEval(interp, cmd, flags)
ARGUMENTS
Tcl_Interp *interp (in) Tcl interpreter in which
to evaluate command.
char *cmd (in) Command (or sequence of
commands) to execute.
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.

DESCRIPTION
Tcl_RecordAndEval is invoked to record a command as an event
on the history list and then execute it using Tcl_Eval (or
Tcl_GlobalEval if the TCL_EVAL_GLOBAL bit is set in flags).
It returns a completion code such as TCL_OK just like
Tcl_Eval and it leaves information in interp->result. If
you don't want the command recorded on the history list then
you should invoke Tcl_Eval instead of Tcl_RecordAndEval.
Normally Tcl_RecordAndEval 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 flags argument contains the TCL_NO_EVAL bit then the
command is recorded without being evaluated.
Note that Tcl_RecordAndEval has been largely replaced by the
object-based procedure Tcl_RecordAndEvalObj. That object-
based procedure records and optionally executes a command
held in a Tcl object instead of a string.
