I tried t

(gdb) br Feval
Breakpoint 3 at 0x8152849: file eval.c, line 2205.o do so:
(gdb) r
Starting program: /mnt/gnu/emacs/src/emacs -geometry 80x40+0+0
[Thread debugging using libthread_db enabled]
[New Thread -1208109376 (LWP 2650)]
[Switching to Thread -1208109376 (LWP 2650)]
Breakpoint 4 at 0x80c88e6: file xterm.c, line 7859.

Breakpoint 3, Feval (form=139269229) at eval.c:2205
(gdb) p form
$1 = 139269229
(gdb) xcar form
$2 = 0x8540b91

Now I wish to do 

(gdb) commands

and here I do not know how to write CONDITION in

  if <CONDITION>
    break
  end
  continue
end

Can you help me a little mode to write the condition please?
