SYNOPSIS

       #include <tcl.h>

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 and Tcl_VarEval.

       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.
