Re: Prototype in RPG/ILE

Peter,

The compiled library/object we are linking to does not contain
prototype information, I don't believe.  That is located in the
source file for the library we built (I'm using Library as a term
for the bound directory, I think, not sure what they are called).
So, the compiler would not only have to find the bound directory
object, but then it would have to find the source code, if you have
it.  If you didn't get the bound directory from another place that
didn't supply you with the source code.  In that case, it would be
impossible without the source code.

Regards,

Jim Langston
