Just as additional info this method also lets you perform this sort of
incremental substitution on letters.

      UniqueID2       = lview.focusedItem.subItems.opIndex(0).text;
      Parent          = lview.focusedItem.subItems.opIndex(0).text;
      Children        = lview.focusedItem.subItems.opIndex(0).text;
      login           = lview.focusedItem.subItems.opIndex(1).text;

let i=97|g/opIndex(\zs\d\+/s//\=nr2char(i)/|let i=i+1

      UniqueID2       = lview.focusedItem.subItems.opIndex(a).text;
      Parent          = lview.focusedItem.subItems.opIndex(b).text;
      Children        = lview.focusedItem.subItems.opIndex(c).text;
      login           = lview.focusedItem.subItems.opIndex(d).text;

let i=65|g/opIndex(\zs\d\+/s//\=nr2char(i)/|let i=i+1

      UniqueID2       = lview.focusedItem.subItems.opIndex(A).text;
      Parent          = lview.focusedItem.subItems.opIndex(B).text;
      Children        = lview.focusedItem.subItems.opIndex(C).text;
      login           = lview.focusedItem.subItems.opIndex(D).text;


:h nr2char
