The brk-level command causes the BREAK key to push a level on subsequent uses. It is not possible to push a level while at the TCL prompt. At least one character must be entered.
On some systems, when the BREAK key is set to push a level, it is not possible to push a level while in the debugger. To push a level while in the debugger, type : and press ENTER.
