gdb asking to continue/quit?

Question

I am new to GDB, using to debug an issue with my program(C++). I used gdb to find the backtrace and then print frames information. During one of the print, let's say the command is something like:

1) frame 2
2) print *this

In between the output of the print call, I am getting the following line:

---Type <return> to continue, or q <return> to quit---

Is this expected from the gdb? We should just continue on that message or it means something?

Note: I didn't set any breakpoint or anything, so didn't expect any message.
