Embedded SQL in C

Initially posed to Oracle 30-day Free Support for folks that download Personal Oracle 7 for Windows NT ... the support folks could not answer the below questions as they apparently deal more with installation/startup
type questions, so I'm hoping someone here can help ... thanks.

• - - - - Hi! Having just downloaded/installed PO7 for WinNT, I've got a quick question on writing Embedded SQL applications using C ...during the installation, I chose the Application Developer (complete) option since I do want to write applications and need more than just the runtime.

Do I need anything else on top on just PO7/NT if I want to               
write Embedded SQL applications in C?  If so, are these products         
also available for free download as PO7/NT was?                          
                                                                         
The 'Pro*C/C++ Getting Started for Windows Platform' manual states       

any way that I can write embedded SQL apps in C without purchasing       
any software (ie trial only)?                                            
                                                                         
Assuming we can get beyond this, I'll be using the 'IBM VisualAge C/C++' 
compiler ... I saw reference to the Microsoft Visual C/C++ and           
Borland C++ compiler in the doc, but do you support the IBM VisualAge  
C/C++ compiler?
