Re: Prototyped Procedures

[rob@xxxxxxxxx]

The "theory" with the api's and other black boxes is that you shouldn't 
have to go into the debug on them.  Much like you don't debug RPG code by 
stepping into the MI (or whatever) to see that you passed the parameters 
on a chain wrong.

Some people want externalized I/O as long as THEY aren't locked out so 
they can see how it works.  Rather one of my points.

I have been working with the record i/o "C" functions recently. In my
testing I was getting some error messages that had no relation to what
I was asking the function to do.  Turns out, I was filling an option
parameter with the incorrect value.    But I could not use the
debugger to find this bug because IBM does not provide the source code
to it C runtime function library.
