# File lib/byebug/commands/frame.rb, line 21 def self.description <<-DESCRIPTION f[rame][ frame-number] #{short_description} If a frame number has been specified, to moves to that frame. Otherwise it moves to the newest frame. A negative number indicates position from the other end, so "frame -1" moves to the oldest frame, and "frame 0" moves to the newest frame. Without an argument, the command prints the current stack frame. Since the current position is redisplayed, it may trigger a resyncronization if there is a front end also watching over things. Use the "bt" command to find out where you want to go. DESCRIPTION end
