Find position of all locations of given character in a string

Friends,

I want to write a formula to find position of all locations of a given character in a string/cell. Find and Search functions give the first occurence of such location.

Eg: If I have "Apple" in A1, I want my formula result as 2,3 if my search string is 'p". FIND("p",A1) will give 1. Search("p",A1) also gives 1.

Can anyone help.

Thanks

The formula still gives position of first or next occurence. I want result as 2 and 3 at the same time.
