[Bug-apl] aplwrap - editing functions with errors

[Blake McBride]

Greetings,

Let's say you create a large APL function using File / New.  If just one
line has an open quote that isn't closed, you lose all of your work.  I
think aplwrap should test the result of ⎕FX before it exits.  If ⎕FX fails,
display the line number with the error and remain in the editor so all of
your work isn't lost.

Thanks.

Blake
