Re: [Bug-apl] Rank error

[Blake McBride]

Yes, I use GIT & SVN all over the place.  I also do daily backups.  The problem I had would have been between any of those backups.

I'm always using source control, even for my personal local projects. That allows me to revert back to previous versions without any problems.

I also use it for my local Emacs configuration. Very useful for keeping my machines in sync.

At times, yes.  The particular case I am in, I am actually editing the .apl file directly because I have a lot of global search/replace operations.  I am migrating some code from one WS to another.  )COPY messed me up bad yesterday.  I ended up throwing away my work and going to a backup.  I am really looking forward to the two )COPY problems being resolved.

Thanks.

Wouldn't it make more sense to edit your code in files, and load it when needed? I.e. to keep the canonical version in the file instead of the workspace.

The fact that you are protected from interpreter crashes should be reason enough I think.

Sorry about that.  I oversimplified an actual case I had.  I'll re-raise the issue if and when I hit it again.  (I don't remember where that was.)

On another note, the two )COPY issues have become a bit of a stumbling block for me.  I actually lost work yesterday because of them.  (I am finishing up an APL editor written in APL.  I would typically load the WS I want to edit, copy  the editor WS, edit the WS, and then ⎕EX the editor.  This doesn't work without a functioning )COPY.  Thanks!)

Thanks.

Hi Blake,

according to IBM [] binds stronger than vector notation (APL2 language reference, page 34).
IBM APL2 also gives RANK ERROR in the examples below. Eg. 1 2 3[2] is evaluateded as 1 2 ( 3[2] ).

Of course, they should all work as if they were assigned to a variable first.
