I need information about pbcat tables in mysql

I need information about pbcat tables in mysql

I have many pbcat(something) tables like pbcatedt , pbcatvld, pbcatfmt,
pbcatcol, pbcattbl in mysql. I need more information about them, I have
discussed them here too, not an answer yet:
http://forums.devshed.com/mysql-help-4/pbcat-tables-in-mysql-951448.html
and here, someone has told me that " Google says that pbc* are from Power
Builder app".

But really need more info, please let me know if there is any
documentation or links for it, I would really appreciate it, really need
these information.
Thank you in advance
