Getting an error from what tool? Quartus? Modelsim? Or what?

Are you trying to just simulate some verilog code or trying to compile/synthesize for a device? If so, what device?

FYI your code may be legal verilog syntax so a simulator may accept it, but it is not synthesizeable verilog.

Structures like this:

pulse = 1;
while (start_clk) begin
    #(clk_on) pulse = 0;
    #(clk_off) pulse = 1;
    end
pulse = 0;

are not valid synthesis structures.
