```Hi,

nonsense, but here
is a version that does this what your explanation
say
Plus @@@ Transpose[
{#2}] &, {list1, list2}]]

{a + b + c + d + e, a + b + c + e, a + c + e, c +
e, c + e, e}

| DearAll,
|
|
| I have two list
|
| list1={a,b,c,d,e}
| list2={3,2,5,1,6}
|
| and I want to apply a modified version of
FoldList to list1 in the
| following way: list2 indicates that element a
appears only 3 times (if
| space enough) beginning from the beginning of
the list , element b
| appears 2 times, c - 5 times , etc.
|
| So the output should be
|
|
GeneralizedFoldList[list1,list2]={a,a+b,a+b+c,c+d,c+e}
|
| Thanks for any hints,
|
| arek
