Volodya,
Below is an example of gdb output in my case:

<font color="blue">(gdb) p Opts.Str</font>
p Opts.Str
$48 = "0X0704 = 4, 
0X00000000\000,0X05060708,0X01020304,0X0D0E0F10,0X0BADDEAD\0000x040d = 8, 
0x04013421,0x02000000\n0x040f = 4, 0x00c80242\n0x040f = 4, 0x00c00942\n0x0104 
= 4, 0x00000000\n0x0105 = 4, 0x00000002\n0x010b"...
^done

I shall be glad to have something similar in format menu. I do not know when 
gdb decides to print '...'. In the above case Opts.Str is 1250 bytes long.
I personally think, that about 20-30 bytes should be enough in variables 
window - if one wants more, there are many other means. This is a quick view 
only.

Regards.
