Re: Question about activestate perl--closed
Mark Jordan and Leif Andersson have pointed me in the right direction. It appears to be a problem with the file folder associations. c:\perl\bin\perl.exe test.pl Hello works, but test.pl Hello doesn't Yet it is weird. 'Cause when the 'Hello' is hardcoded inside the file, it works fine. Oh well, thanks folks. Will pursue this with my local PC support gurus. Anne L.

Re: Question about activestate perl
I think shift applies to an array, not to an argument. Try #!/usr/local/ActivePerl-5.8/bin/perl -w my $test = $ARGV[0] ; print "$test\n"; to read the first argument (hello) from the array ARGV Sincerely, Arno H.P.

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 Mark Anne L.

But this works in my installation of ActiveState Perl: my $test = <>; print "$test\n"; I think $ARGV() is used for command line parameters. -- Saiful Amin +91 9343826438
