Certain commands to gdb may produce large amounts of information output to the screen. To help you read all of it, gdb pauses and asks you for input at the end of each page of output. Type [RET] when you want to continue the output, or q to discard the remaining output. Also, the screen width setting determines when to wrap lines of output.
