Should I switch

One other option you might consider: Change the dynamic array to a
dimensioned array. Some environments allow you to dimension on the
fly (i.e., MAX = 200; DIM D.ARRAY(MAX)).


I most wholeheartedly agree; it is most gratifying how much faster an
app runs when you quit using dynamic arrays that you tend to find
growing beyond, say, 100 kb or 1 mb.

Indeed. The entire dynamic array is a single variable whereas each
element of a dimensioned array is a single variable.
