tie on windows XP

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

I am using ActiveState Perl 5.16.1 on windows XP. The function dbmopen meets my immediate requirements for a persistent hash. The perl documentation states that this function is largely superseded by tie. None of the modules (*DBM_File) are in the PPM repository. (I assume that this is because the data bases they require are not available) I want to know if it is even possible for me to use tie for this purpose. If so, does it offer any real advantage. And if it does, what do I have to download and how do I use it.

Update: Corrected perl version number.

Bill

I think at least DBM_File or GDBM_File should be available to you - at least, GDBM_File is available with my Strawberry Perl 5.16. Alternatively, you can look whether DBM::Deep is available from PPM. tie is a far more general mechanism that can be used to produce the mechanism that dbmopen used to produce, but its power is far larger than that.

Thanks for the suggestions, but there are no DBM_File modules in the repository. Since my first post, I have found SDBM_File.pm in @INC. I do not know how it got there, but it works as advertised. Bill	[reply]

G'day Bill, Both DB_File and SDBM_File are builtin modules that ship with Perl. I don't have your Perl/OS combination so I can't really comment on the PPM repository; however, if builtin modules are not normally available via PPM, that would at least explain the absence of `DB_File` and `SDBM_File`. That would also shed some light on your later comment: "I have found SDBM_File.pm in @INC. I do not know how it got there". -- Ken	[reply] [d/l] [select]
