# File 'lib/byebug/commands/frame.rb', line 197 def description prettify <<-EOD f[rame][ frame-number] Move the current frame to the specified frame number, or the 0 if no frame-number has been given. 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.
