I have an editor that I think is pretty good (Optiperl) The problem is
that when I paste it into the e-mail, the mail program (The Bat) makes
a mess that can not be edited within the mail program. This is my only
serious complaint about the bat and I am too committed to change
programs. I did a lot of pre-editing to make it less of a mess. When I
paste it in, it still messes up the indenting and I can not edit it
without making a total mess.
The pasted code is part of a much larger program that uses MIDI perl.
All variables are declared and have appropriate scope. I simplified
the following a little. My only question is why the same assignments
to an array work fine in one way and not the other. I had two lines
swapped in the original example but I had tested both orders and they
worked the same so I made them consistent in this example so as to not
call attention to that as a possible difference. I would like to
figure out what causes the problem so I can find a solution faster the
next time something like this happens. I re-wrote the code about 20
times before I tried moving the array assignment to another block. The
various temporary arrays (on_off_time and note_array) are initialized
and modified outside of the example shown and this all works as it
should. To show what the program really does would require a very
large example which would not make the problem clearer.Lists <[EMAIL PROTECTED]>
