The $! command displays the current
call stack with parameter names and values being shown. If the symbol
table is not present, the internal names are shown.
Note: flash.routine.name can only be
specified if the program has been optimized through the FlashBASIC
compiler. When flash.routine.name is specified,
the corresponding debugger command is executed against the specified
routine. The colon separating flash.routine.name and the debugger command is required.
