This is a subroutine from a program of mine and it's call. Why does -w give me an uninitialized value error, I defined it correctly. The program works right if I turn off -w. #!/usr/bin/perl
print CalcBalance(\"balance.log");
sub CalcBalance {
my ($balance, @log);
my $location = 0; #because my $location = shift(@ARGV) does not w
+ok either.
$location = shift(@ARGV);
# the following is not needed
# open (RBALANCE, $location);
# @log = <RBALANCE>;
# $balance = $log[-1];
# close (RBALANCE);
# if (@ARGV && $ARGV[0] != 0) { # we check to see if there is a
+nother
# # argument (the amount to change) a
+nd
# # it is not 0.
#
# my $toChange = shift (@ARGV); # we only declare this if another
# # argument exists to make the test
# # above work.
# $balance += $toChange;
# open (WBALANCE, ">>$location");
# print WBALANCE $balance;
# close (WBALANCE);
# }
}
Thanks

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
