Cannot specify --frame without --thread

Cannot specify --frame without --thread

[Mahmood Naderan]

Hi,
I have started gdb with this command:

gdb --interpreter=mi2

The complete list of commands I used is pasted below. Please have a look at the end of message where I get the error.

Is there any way to fix that?

The following section of the GDB manual doesn't say explicitly
