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 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.
