#{NAME} [breakpoint position]

Leave the debugger loop and continue execution. Subsequent entry to
the debugger however may occur via breakpoints or explicit calls, or
exceptions.

If a parameter is given, a temporary breakpoint is set at that position
before continuing. 

Examples:
   #{NAME}
   #{NAME} 10    # continue to line 10

See also 'step', 'next', and 'nexti' commands.
