It seems like the natural thing here is to pass your desired target handle as an argument to the subroutine rather than using a closure -- see
perlsub for info on how to use subs in Perl. Your code might look like:
sub write1 {
my $STH = shift;
while ( @data=$STH->fetchrow_array() )
{
print "<CENTER>";
print "<TR>";
print "<TD BGCOLOR='red'>";
print "<P ALIGN='CENTER'>";
print "<FONT COLOR='white'>";
}
}
Alternatively, if you mean a closure that systematically goes over three previously defined statement handles, you can wrap your while loop in a foreach loop like:
sub write1 {
foreach my $STH ($STH1, $STH2, $STH3) {
while ( @data=$STH->fetchrow_array() )
{
print "<CENTER>";
print "<TR>";
print "<TD BGCOLOR='red'>";
print "<P ALIGN='CENTER'>";
print "<FONT COLOR='white'>";
}
}
}
