The best I can come up with on the fly would be something like this:
---
#!/usr/bin/perl
use strict;
use warnings;
my @test = ('A123C.11+002.001','FC32G.2-1.0','12B15.01+2145.15');
foreach my $item (@test)
{
print "$item\n\n";
($a,$n,$x,$y)) = $item =~ /(.{5})\.(\d\d?)[-+](\d{1,4})\.(\d{1,4})/;
my ($lengthx, $lengthy) = (length $x, length $y);
print "a = $a, n = $n, x = $x, y = $y, length x = $lengthx, length y =
$lengthy\n";
}
---
But the real experts can probably compress it much more still.
