sub bin_urls {
foreach (@alpha) {
$temp = "> $_.out";
open ($fh, $temp);
print $fh "Delete the file and replace it with this line";
close($fh);
}
}This was likely added to Perl due to the popularity of the "use FileHandle;" stuff $Bill mentioned in his reply... but doesn't require that module. TMTOWTDI.

Hi Dominic
The filehandle is basically a pipe to the file and to the best of my knowledge cannot be a variable. The loop in question should be something like this.
sub bin_urls { foreach (@alpha) { $temp = "> $_.out"; open (FH, $temp); print "Delete the file and replace it with this line";
^ don't you need a FH there when using this technique?
close(FH); }

Hello,
I am experiencing serious problems when using the strict pragma with file
handles -- I have read up on the topic, but no solutions.
#!/usr/bin/perl use strict;
@alpha = ("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m",
"n",
"o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z",
"misc");
<snip>
# clean up and bin urls sub bin_urls { open (FH, "test_data"); # this works fine foreach (@alpha) { open (FH.$_, ">$_.out"); # errors with "Can't use string (FH.a) as a
symbol ref
# while strict refs in use..." }
<snip>
Basically, I need to use a variable for the file handles name -- seems
like this should work. If I do not use strict, the code runs fine...when I use strict, the error listed above is returned. What am I missing?
Thanks, Dominic
