If q is a std_(u)logic_vector, you can write

--- Quote Start ---

q <= "1001";

--- Quote End ---

which type is your variable ? maybe you have to "transtype", for exemple

--- Quote Start ---

q <= std_logic_vector(variable);

--- Quote End ---

if variable is unsigned(3 downto 0).

Your 'reset' seems to be active low (when its value is '0', the reset is active), because of voltage controller and/or (in your case) push button usually sets to 0.

In an other way, you probably have a reset_n button.
