> I am not familar with OPRO, APRO, TTT OR RTL.  What are they?

      OPro and APro are programming toolkits from Turbo Power Software,
Object Professional and Async Professional.  TTT is another toolkit from
Technojock Software.  RTL is the run-time library source code that is
included with Borland Pascal.  The OS/2 patch uses a highly modified
version of the RTL.

 > Is BPOS2 what this German co. calls there product now?

      When you run the patch on your Borland Pascal compiler and IDE, it
changes the BP 7 to BPOS2.  It's still the Borland product with the ability
to generate windows code replaced by 16-bit OS/2 capabilities.
