Elisha,
You can concatenate the arrays, as you suggest:
a = [[1,2],[3,4]]
a = [[a],[5,6]]
help,a
==>A INT = Array[2, 3]
However, if you have many elements, this can be very resources
consuming. Another option is to create a "big" 2*n array, to
progressively fill it, to keep a counter on the number of entries, and
finally to cut what you haven't used.... and similarly, if your array is
not big enough, add a large number of rows and keep filling them (use
the same concatenation method as above)
