Frequently Asked Questions

Can I access one dbf file both from Perl and (say) Clipper?

AnnoCPAN - XBase::FAQ
For reading -- yes. For writing -- XBase.pm has a locksh and lockex method to lock the file. The question is to what extend Clipper (or Fox* or whatever) uses the same system calls, documentation of native XBase applications doesn't tell this. So the answer is that for multiple updates you should probably consider real RDBMS system (PostgreSQL, MySQL, Oracle, to name a few). No, it doesn't. The character data is returned exactly as it appears in the dbf/dbt file.

Why I cannot open the fixed DBF file?

Frequently Asked Questions
If your DBF file is created by one application, but you want to open the fixed file in another application, then you may fail. The solution is to set the correct version in the combo box beside "Select DBF to be repaired" edit box according to the second application and then start reparation again. For example, your DBF file is created by Clipper but you want to open it in dBase III, then you need to set "Version" to "dBase III" and then repair the file again.

How do I pack the dbf file, after the records were deleted?

AnnoCPAN - XBase::FAQ
