seek_positions = {}
for element = 1 to length(string) do
     if find(string[element],vowels) then
          seek_positions = append(seek_positions,{element, string[element]})
          string[element] = ' '     
     end if
end for

Here we are building a 2 element sequence called seek_positions.

the first element being the element number.

the second element being a string (' ')

in the code 
seek_positions[1][1]=1
seek_positions[1][2]=' '

seek_postition[2][1]=2
seek_positions[2][2]=' '

etc...

so seek_positions[2][1]-1=1
   seek_positions[5][1]-3=2
