NAME
     Tcl_AllowExceptions - allow all exceptions  in  next  script
     evaluation

SYNOPSIS
     #include <tcl.h>

     Tcl_AllowExceptions(interp)

ARGUMENTS
     Tcl_Interp   *interp      (in)      Interpreter   in   which
                                         script      will      be
                                         evaluated.

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_CONTINUE  or TCL_RETURN, then Tcl normally con-
     verts this into a TCL_ERROR return with an appropriate  mes-
     sage.

     However,  if  Tcl_AllowExceptions  is  invoked   immediately
     before  calling a procedure such as Tcl_Eval, 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.


KEYWORDS
