Hello Wayne,

you can do this:

IDL> st = {flux:ptr_new()} ;Create a structure with a pointer
IDL> st = replicate(st,20) ;I want a structure with 20 elements
IDL> st.flux=ptrarr(n_elements(st),/allocate) ;Allocate all pointers
IDL> help,st[0].flux
<Expression> POINTER = <PtrHeapVar1>
IDL> help,st[4].flux
<Expression> POINTER = <PtrHeapVar5>

Cheers, Heinz
