NAME

     Tcl_RecordAndEval - save  command  on  history  list  before
     evaluating

SYNOPSIS

     #include <tcl.h>

     int
     Tcl_RecordAndEval(interp, cmd, flags)

ARGUMENTS

     Tcl_Interp *interp (in)          Tcl interpreter in which to
                                      evaluate command.

     const 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  do  not  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  the  interpreter's
     result.  If you do not want the command recorded on the his-
     tory  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.
