I am trying to port some old code from MatLab to J. It seems that it
should be easy, but I am finding one aspect of it difficult.
In MatLab I used their data structure with several sub-levels. Four
features seemed very nice to me: 1, Many constants could be associated
with a single overall name (say q1.) . 2, I could add new ones at will
(say q1.test). 3, I could duplicate the whole thing with a single
assignment (say q2 = q1). 4, The hierarchical nature of the structure
is as obvious as it is easy to make or use.
I assume that the use of locales is the answer to providing a similar
facility in J. I am aware of the examples like plot that keep the plot
variables in its own locale , but I must be missing some fundamental
concept as I have struggled with this for a few days and cannot quite
get my arms around it.
Thanks,
Dave Porter
