IDL has a peculiar naming procedure for the field element in the structure
returned by "read_ascii" when you do it without a template. Put a "stop"
after yopur call to "read_ascii", and when the program halts, type in

help, archivo, /struct

This will tell you the field name (I think it will be something like
field001)
