In Powerbuilder, how do I access the C# code to correct these errors?

I am trying to deploy a winform target but have been getting these errors:

 ---------- Error messages:    (9:56:07 AM)
Error when compiling generated C# code:
app(18,120): error CS1040: Preprocessor directives must appear as the first non-whitespace character on a line

app(25,45): error CS1026: ) expected
app(25,45): error CS1003: Syntax error, ']' expected

Can i access the C# code to correct these issues? I have found all the CS messages and have an idea how to fix them, but I cannot find how to get to them in PB.

Thanks for your help.
