Which loop is better ?

From an Input let's say '3' i want to display a product of that input from 1 to 10, but i want to skip the 5th iterration.
I made two loop and i would like to know if there is one that is better than an other in term of optimisation...

And yes i have already declare all variables and parameters.

Thanks

Loop1

WHILE v_y <= 10 .            " Loop the into the v_y  until it is equal 10

  IF v_y <> 5 .              " We check if v_y is different than 5
    v_res = p_x * v_y .
    WRITE :/ p_x,'*',v_y,'=',v_res .
  ELSE.                      " If v_y = 5 we skip and we do nothing

  ENDIF .
  v_y = v_y + 1 .            " We increment the v_y to go to the next number
ENDWHILE .

Loop 2

WHILE v_y <= 10 .            " Loop the mutiply until variable equal 10

  IF v_y = 5 .              " We check if v_y is different than 5
    v_y = v_y + 1 .         "We increment the v_y
    CONTINUE.
  ENDIF.
    v_res = p_x * v_y .
    WRITE :/ p_x,'*',v_y,'=',v_res .
    v_y = v_y + 1 .            " We increment the v_y to go to the next number
ENDWHILE .

You should not waste time in optimizing few microseconds... Focus on expensive constructs only.

thank you sandra.rossi ,

what are you calling expensive construts ?

expensive = database access, etc.
