Hi Gary - thanks for your reply. I think my initial explanation may have been unclear, as this is not the solution to my problem. The problem reduces to the following: I don't know explicitly which variable (I incorrectly referred to this variable as an element previously, hence the confusion) I want to update, so I can't say
circle%radius = <something>
All I have is an index that tells me I need to update the i^th variable within the derived type. So say I need to update circle%z, the index would have value 4. But I know that I can't do
By i'th variable, are you saying the i'th component? No you can't alias an index with the formally defined components and have value 1 refer to radius and value 2 refer to x. You could use select case to make that choice based upon the index. Still not sure I understand fully tho.
