dsetsegmentsize
.SETSEGMENTSIZE num
command. Sets the number of nodes that Logo allocates from the
operating system at once to num, which must be a positive integer.
The name is dotted because bad things will happen if you use a
number that's too small or too large for your computer. The
initial value is 16,000 for most systems, but is smaller for
68000-based Macs. Making it larger will speed up computations
(by reducing the number of garbage collections) at the cost of
allocating more memory than necessary.
