Re: Question about activestate perl

Hi Anne,

Your script works (on my WinXP instance of ActivePerl anyway) when you 
replace the unix-style shebang line with the windoze equivalent, e.g.,

#!c:\perl\bin\perl.exe -w

my $test = shift;
print "$test\n";

Or, you can remove the shebang totally and run

perl anne-test.pl
