Here are two ways to do it:

1 Using make_array():
First define your structure by defining a scalar.
e.g., rec = {structname,name: "John Doe",tel:5551234}
(You could also use an anonymous structure scalar.)
Then do recs=make_array(N,val=rec), where N is the number of elements you
want in your array of structures. (Of course, you don't have to stick
to a 1D array.)

2 Using replicate()
Set up your structure scalar "rec" as in (1), then do recs=replicate(rec,N).
