Sorry, looks like what I typed looks gibberish in places. I hope this
one is more readable:

Hi All,

I have a problem referencing structure arrays and assigning values to
them. So here is a snippet of my code:

junk1=update_state(junk) ;creates a structure called junk1
statearr=replicate(junk1,3) ;creates an array of structures

infoptr=ptr_new({statearr:statearr}) ;need this to pass variables
between programs

align_images,state=state1 ;some program that aligns 2 images and
stores the alignment results in state1

;assign values from the state1 structure to infoptr.statearr[0]
structure
(*infoptr).statearr[0].resvol_file_ptr=state1.resvol_file_pt r
(*infoptr).statearr[0].air_file_ptr=state1.air_file_ptr

Now, here is the problem. With the above code, it turns out that...

(*infoptr).statearr[0].resvol_file_ptr, (*infoptr).statearr
[1].resvol_file_ptr, (*infoptr).statearr[2].resvol_file_ptr
all have the same values. Similarly with air_file_ptr. Even though I
haven't assigned anything to the statearr 1 and 2 yet.

Is there a specific way to reference these structure arrays? Any help
is greatly appreciated!

Thanks
Niv
