print "1..4\n";

$x='banana';
$x=~/.a/g;
if (pos($x)==2) {print "ok 1\n"} else {print "not ok 1\n";}

if (f(pos($x))==4) {print "ok 3\n"} else {print "not ok 3\n";}

# Is pos() set inside //g? (bug id 19990615.008)
$x = "test string?"; $x =~ s/\w/pos($x)/eg;
print "not " unless $x eq "0123 5678910?";
