How can I generate several Perl filehandles programmatically?

Question

Is there any way in Perl to generate file handles programmatically?

I want to open ten files simultaneously and write to them by using file handle which consists of (CONST NAME + NUMBER). For example:

 print const_name4  "data.."; #Then print the datat to file #4

You can stick filehandles straight into an uninitialised array slot.

my @handles;
for my $number (0 .. 9) {
    open $handles[$number], '>', "data$number";
}

Don't forget that the syntax for printing to a handle in an array is slightly different:

print $handles[3] $data;    # syntax error
print {$handles[3]} $data;  # you need braces like this
