You can use my reform_struct.

; CATEGORY:
; PROG_TOOLS/STRUCTURES
;
; CALLING SEQUENCE:
;
result=reform_struct(structure,dim1,[dim2],[dim3],[dim4],[di m5],[dim6],[dim7],[dim8],[/struct_array],[/tag_array]
;
; INPUTS:
; structure: a structures
; dim1: the new dimension of the input structure (1D to 8D)
;
; OPTIONAL INPUTS:
; dim2 to dim8: additional dimensions if not declared in dim1
;
; KEYWORD PARAMETERS:
; struct_array: if is set output structure is an array
; tag_array: if is set output structure is 1D and tags are arrays
; You have to set one of these keywords

In that case you might want to create a single-element structure d at
the time you create the ccc array structure. Then you could do
something like
ddd = replicate(d, 133)
for i=0L, n_tags(ccc)-1 do ddd.(i) = ccc.(i)
Alternatively, create the single-element structure d from ccc in a
FOR-loop using TAG_NAMES() and repeated structure concatenation by
CREATE_STRUCT(). Or create the d structure in an EXECUTE() call.

Thanks Jaco,
That's the way I am doing it now. But I have some 50-60 tags and they
are sometimes different from structure to structure...

how about:
ddd = replicate({name:'', ra:0.d}, 133)
ddd.name = ccc.name
ddd.ra = ccc.ra
cheers,
