Dear Masters,

I have a Perl script that takes a binary and output the result to an array.

To simplify the matter, the binary only takes one parameter.

Now the problem I had is this. When I ran the binary straight from the shell with both parameter (A and B), like this:
  > some_binary.out A

   or 

  > some_binary.out B

[download]
Both of them gave some output as expected. But when I ran it on Perl script: 
#!/usr/bin/perl -w       

# aboved changed thanks to Mandrake

use Data::Dumper;

my $param  = 'A';  
# When I replace 'A' with 'B', it gives no output


my @output = `some_binary.out $param`;
chomp @output;

print Dumper \@output;

# gives $VAR1 = []; with 'B'

[download]
Only param 'A' gives some output, not 'B'. What could possibly cause this erratic behaviour? How can I effectively debug it?
