Hi, given the same identical input string, why does the following line return an array with 2 elements:

my @parts=($sysex_dump =~ /\xF0C.[~z](..LM  0087[A-Z][A-Z].+?)(..LM  0087[A-Z][A-Z].+?)\xF7/gs);

While this line only returns an array with the first of the above two elements:

my @parts=($sysex_dump =~ /\xF0C.[~z](..LM  0087[A-Z][A-Z].+?)+\xF7/gs);

I would have thought the '+' after the bracket should match more than once and assign all matches to the array?

How do I get the second pattern match to assign all matches as multiple elements to the array?

Edited to add a self contained code example (the print and the for loop are just to check the array I get):

my @parts=("\xF0C.z..LM  0087AAaaa..LM  0087BBbbb\xF7"=~ /\xF0C.[~z](.
+.LM  0087[A-Z][A-Z].+?)+\xF7/s);
print STDERR @parts." parts\n";
for($a = 0; $a < @parts; $a++) {
print STDERR ($a+1).": ".length($parts[$a])." length\n";
}
