I must store big J array (1000000 * 10 ) data in mapped files because
it is the only way to store big arrays where the size is beyound of
limits of jfiles .
However I meet a problem when I try to copy data from a mapped file
to J workspace.
After mapping and assign: my_noun =: mapped _noun. The probelm is to
unmap mapped_noun and keep the data in my_noun for further
manipulation. The problem os obviously tat the data is not copied to my_noun.
What is the fastest way to say my_noun =: mapped _noun so that the
data is really copied to my_noun?
