Hi, I have this snippet of code which actually works, but I would like to
get rid of the warning....
[PbFe]$ more foobar.pl
#!/usr/bin/perl -w
#my $helloworld;
my $hello='helloworld';
${$hello}='foo';
print STDOUT $helloworld."\n";
[PbFe]$ ./foobar.pl
Name "main::helloworld" used only once: possible typo at ./test.pl line 7.
foo
[PbFe]$
Kinda neat, dont you think? Even if I dont get an answer, it may help some
other poor perl beginner..... As you can see, I tried to define
$helloworld to fix this problem, but get the following error when run:
Can't declare scalar deref in my at ./foobar.pl line 4, near "}="
Execution of ./foobar.pl aborted due to compilation errors.
Any ideas?
A.
