syntax or algorithm ?

This should implement your algorithm: restart; w:= 4: w1_lst:=NULL: for k from 1 to 10 do for h from 1 to 20 do for a from 4 to 15 do w1:= a + h: #h, not hk w1_lst:=w1_lst,w1: if w1< w then w:=w1: else w:= w: #redundant end if: end do: end do: end do; w1_lst; But your algorithm is wrong in at least two regards: first you used h as a loop counter but hk inside the loop. Second, the "else" statement is redundant, so maybe you wanted to do something different or maybe you just don't need it.

whitespace

My code above was indented when I posted it, and the indents are still there when I edit it; only they disappear when displayed after posting. What's up with that ?

thanks

the algorithm works! thanks a lot

formatted

Change the Format to "formatted" instead of Normal.

restart;

w:= 4:

w1_lst:=NULL:

for k from 1 to 10 do

  for h from 1 to 20 do

    for a from 4 to 15 do

      w1:= a + h:  #h, not hk

      w1_lst:=w1_lst,w1:

       if  w1< w then w:=w1:

       else w:= w:  #redundant

       end if:

    end do:

  end do:

end do;

w1_lst;
