I have submatch index in a variable, $SUB=5. How do I write submatch

Is ${$SUB} ok ?

What happened when you tried it?

2. Is there array of subpatterns ($1..$<N>) so I can take it's size ?

Just evaluate the pattern match in list context.

my @matches = $x =~ /(foo).*(bar).*(baz)/;
print "Found " . @matches . " matches\n";

If that's not what you meant, please post a short-but-complete program
that demonstrates what you're trying to do and how you're having
difficulty.
