Hi folks
Howdy.

I've got a query about variable initialisation. I want to initialise a 
list of
variables to an empty string, but I'm having troubles.

What's the best wat to do this?
How about:

my($fred, $ginger) = ('') x 2;

 If I use the following I get:

[EMAIL PROTECTED] gary]$ cat t
#!/usr/bin/perl -w
use strict;

my $fred=$ginger='';

print "fred=$fred\n";
print "ginger=$ginger\n";
[EMAIL PROTECTED] gary]$ ./t
Global symbol "$ginger" requires explicit package name at ./t line 5.
Global symbol "$ginger" requires explicit package name at ./t line 8.
Execution of ./t aborted due to compilation errors.
[EMAIL PROTECTED] gary]$
but if I use:

[EMAIL PROTECTED] gary]$ cat t
#!/usr/bin/perl -w
use strict;

my ($fred,$ginger)='';

print "fred=$fred\n";
print "ginger=$ginger\n";
[EMAIL PROTECTED] gary]$ ./t
fred=
Use of uninitialized value in concatenation (.) or string at ./t line 
8.
ginger=
