Dear Marianne
In our library are lots of routines for structures and their tags.
; NAME:
; reform_struct
http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/reform_struct.tar.gz
http://www.fz-juelich.de/icg/icg1/idl_icglib/idl_source/idl_ html/dbase/download/reform_struct.sav
;
; PURPOSE:
; This function is used to reform a structure as tag array or
; struct array
;
; CATEGORY:
; PROG_TOOLS/STRUCTURES
;
; CALLING SEQUENCE:
; result=reform_struct(structure,dim1,[dim2],[dim3],[dim4],$
; [dim5],[dim6],[dim7],[dim8],[/struct_array],[/tag_array]
;
; EXAMPLE:
; data=create_struct('A',FINDGEN(15),'B',SIN(FINDGEN(15)))
; result=reform_struct(data,15,/struct_array)
; HELP,result
; RESULT STRUCT = -> <Anonymous> Array[15]
tmp={a:findgen(15)}
tmp=reform_struct(tmp,15,/struct_array)
tmp2={a:tmp,b:1}
help,tmp2,/str
** Structure <1353068>, 2 tags, length=64, refs=1:
A STRUCT -> <Anonymous> Array[15]
B INT 1
The following routines are useful for non arrayed structures.

tmp2={BB,CC:replicate({AA,a:1,b:2},12)}
then you can do
tmp2.cc.a=findgen(12)
etc. But you'd better hope you don't later want 11 or 13 AA's, because
without pointers, you're stuck.
