Ahh, good point ;-)

Serves me right for trying to be creative on a Windows box sans Perl :)

This is the variant I found most straightforward to use:
```use List::Util qw[min max];

\$m = max(1,2);

Here you go:

This is how one can find a maximum number in an array iteratively and recursively in Perl

```
#!/usr/bin/perl

my (@setOfnumbers);

@setOfnumbers = ( 9, 7, 90, 3, 8, 412, 67, 2, 45, 53, 1, 3,89 );

print "Finding maximum number iteratively ",
getMaximumNumber(@setOfnumbers) , "\n";
print "Finding maximum number recursively ",
findMaximumNumber(@setOfnumbers) , "\n";

#Finding maximum number iteratively
sub getMaximumNumber{
my (\$maximumNumber);
\$maximumNumber = @_[0];
foreach(@_){
if (\$_ > \$maximumNumber){
\$maximumNumber = \$_;
}
}
return \$maximumNumber;
}

#Finding maximum number recursively
sub findMaximumNumber{

my (\$maximumNumber);

if (@_ == 1){
\$maximumNumber = shift(@_);
return \$maximumNumber;
}
else{
\$maximumNumber = shift(@_);
return (findMaximumNumber(@_) > \$maximumNumber)
? findMaximumNumber(@_) : \$maximumNumber;
}

}
