using 'our' on Win32 vs Unix

djbiv has asked for the wisdom of the Perl Monks concerning the following question:

ok.. not sure why this works on one system vs. the other. I have an application that should run on Win32 as well as *NIX systems. I declare several hash's using 'our %some_hash' and the associated values for the hash. here is an example:

our %hash = (
      '1' =>'F,n,4',
      '2' =>'LL,n,19'
);

this runs fine on Win32 system but when I run this on AIX I get the following error(s):
Bareword "our" not allowed while "strict subs" in use at program_name.pl line 139.
Bareword "fldFmt" not allowed while "strict subs" in use at program_name.pl line 139.
Operator or semicolon missing before %fldFmt at program_name.pl line 139.
Ambiguous use of % resolved as operator % at program_name.pl line 139.
Global symbol "%fldFmt" requires explicit package name at program_name.pl line 628.
Execution of program_name.pl aborted due to compilation errors.

perl on win32 is "v5.6.0 built for MSWin32-x86-multi-thread" and the version on AIX is "version 5.005_03 built for aix". Why do I get errors on one system vs. the other? Is this due to perl version / build differences?
PS. the program is runs fine using 'my' to declare the hash on both systems (technically the hash should be declared as a global according to programming perl by O'REILLY).

Is this due to perl version / build differences? Correct - `our` wasn't introduced into perl until 5.6.0. In the mean time you could use `vars` or just fully declare your variables `use vars qw/%hash/; %hash = ( ... ); ## or %Your::Package::hash = ( ... );` [download] See. `perldelta` on your windows machine to for more information on the addition of `our` and any other changes between the two versions.

I am not positive but I think 'our' is a later enhancement than your Unix version. You can `use vars qw( %hash );` to make strict happy, but its not exactly the same as our. Alternately, of course, newer perls do support 'our'.	[reply] [d/l]
