Hello All,
I was trying to write this perl program and got stuck with it. Basically,
this program does the following
[1] Get the list of files from the dir that matches the file search
[2] Builds a string and calls another perl program (DBFTP.pl) which then
FTPs the file.
[3] Repeats [2] for each
Fortran can use any indices you want by declaring it as
real foo(-10:10)
and has been able to do that for years.

When doing something like this, the easiest way to do it is to create an indexing
function negind as in following example
#!perl -w
my @array=(-3,-2,-1,0,1,2,3);
sub negind ($\@) {
my $offset=shift;
my @negarr=@{+shift};
my $indoff=$offset + int (scalar @negarr)/2- 0.5;
One approach to having a true-negative indexed array is by defining
an object-oriented approach. A set of tied-array-based methods might
provide the most natural approach. That should allow a transparent mapping
of negative array indices onto a perl zero based array implementation
while avoiding a
How much detail would you like, Mr Cernansky?
I'm creating variable sized gaussian masks for
image transformations. I'm currently using an
offset to index, but I don't want to do that, as
it's ugly to read. I'm only using Perl for prototyping
a larger image recognition project, but perhaps that as
That was a really useful suggestion: thanks, Carl.
Scoping it seems to be the problem. I'll have a look
for a good CPAN search engine.
Thanks

What's the difference which way it is if you access it only by
using negative offsets ?
Not *only* negative offsets.

I don't know of a module, however you might look at perldoc perlvar
for the info on $[. This is the index of the first element of an
array, normally, and by default 0. However I don't see anything
that says $[ can't be set to an arbirtary value. It will, however
affect the index of the first elemen
>From the limited detail you're providing, it seems that perhaps a hash
is actually what you want anyway. What are the minimum and maximum
values of your indices? If you have a known min and max, you could
create an array whose indices could be offset by a constant. But that
seems like a big pa
