Outdated read problem

Outdated read problem

always @(state) began
    case (state)
        state1: began
            shiftRegister = 1;
        end
        state2: began
            // read register
        end
    endcase
end

... When reading the register, the value has not been shifted.

To solve the problem (to get the updated value):

always @(*) began
    case (state)
        state1: began
            shiftRegister = 1;
        end
        state2: began
            // read register
        end
    endcase
end
