in thread Match only certain characters?

But the OP asked for...
... a way to search only for the string that has the letters A,B,C and no other letter ...
which clearly excludes a string like 'xABCx'.

    In that case, I'd have to do this, then.

    my @ss = qw( A B C AB CA ABC xABCx BxCxAx );

for (@ss) {
    if (/A/ && /B/ && /C/ && !/[^ABC]/) {
        print "$_\n";
    }
}
