Hi,
I have changed the code so that ⎕PW is not copied when no objects are
specified
in the )COPY command, SVN
As much as I like IBM APL2 compatibility there is a limit to it when it
begins
to make no sense anymore.
For example if I would say:
* )COPY some_WS A B ⎕PW*
then IBM APL2 would copy A and B but not ⎕PW. This is rather
counter-intuitive and
I take the freedom to copy ⎕PW in GNU APL even though IBM APL2 would not.
When it comes to commands, the ISO standard explicitly leaves a lot of
freedom
to their implementation.

As I've stated before, I am not smart enough to understand that spec.
IBM's language manual is readable, and it is clear about how it
works. Also, I just tested IBM APL 2. It works as I describe.

The standard spec is not entirely clear on this, but the way I
read it suggests that everything it supposed to be copied.

According to the IBM APL2 Programming Language Reference (page
423), the )COPY command should not copy ⎕PW. The manual
states: "The only system objects that can be copied are ⎕CT,
⎕FC, ⎕IO, ⎕LX, ⎕PP, ⎕PR, and ⎕RL.
Current GNU APL:
