DESCRIPTION

       If  a  script  is evaluated at top-level (i.e. no other scripts are pending evaluation when the script is
       invoked), and if the script terminates with a completion code other than TCL_OK, TCL_ERROR or TCL_RETURN,
       then  Tcl  normally  converts  this  into a TCL_ERROR return with an appropriate message.  The particular
       script evaluation procedures of Tcl that act in the manner  are  Tcl_EvalObjEx,  Tcl_EvalObjv,  Tcl_Eval,
       Tcl_EvalEx, Tcl_GlobalEval, Tcl_GlobalEvalObj, Tcl_VarEval and Tcl_VarEvalVA.

       However,  if  Tcl_AllowExceptions  is  invoked immediately before calling one of those a procedures, then
       arbitrary completion codes are permitted from the script, and they  are  returned  without  modification.
       This  is useful in cases where the caller can deal with exceptions such as TCL_BREAK or TCL_CONTINUE in a
       meaningful way.
