work with structures [message #73610]

I have a program that takes a structure as one of its argument. I want
this program to parse and display its contains.

The structue may looks like this:

structure = { var1: {label:'label of var1', value:'value of var1'},$
var2: {label:'label of var2', value:'value of
var2'},$
... }

I'm not supposed to know in advance the name of var1. Using tag_names,
I was able to retrieve those names, but know I need to get the label
and value of each of them and this is where I'm stuck.

of course doing something like

list_var = tag_names(structure)
for i=0,n_tags(structure)-1 do begin
print, structure.list_var[i].label !!! not working
endfor

did not work !

Any idea how I can do that ?
