It will remain the value before enable signal switches.

Hi,
i read some vhdl code of the opencore HDLC and now i have
a question regarding process stements and how the hardware looks
like.

..
proc1: process (txclk, rst_n)
variable state :STD_LOGIC

if rst_n = ??then
  state    := '0';
  signal1 := '0';
 elseif txclk'event and txclk = '1' then
  if enable = '1' then
      state    := '1';
      signal1 := '1';
  end if;
 end if;
end if;

What values have state, signal1
if the enable signal switches to '0' ?
There is no elseif statement for that !!
Thanks.
