Re: ProC Declaring host arrays in a separate class

Ed:

Thanks for the reply.

I did run the ProC pre-compiler, on the .PC file. the problem is, it does not alter the declaration in a .H file.

I need to clarify my question a bit. What I want to do is to declare host arrays in Class A. Then, in Class B, create an instance of Class A, then bind the host arrays in Class A in a method of Class B.

As far as I know, this means I need to declare the variables in the Header file for class A, include it in class B, then somehow, tell the ProC compiler I need to do:

SELECT ID FROM FOO INTO :instanceOfA->HostArray

Thanks in advance!
