The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Not sure what you mean by "other consequence" ...
The consequence is that don't copy the prototype into the source with
the procedure, and then you change the parameters for the procedure
code, then even if you think you have made a matching change in the
prototype that all the callers are using, the compiler can't verify that
the caller prototype matches the procedure.
So if you get the change to the prototype wrong, or if you completely
forget to change the prototype, you'll get parameter mismatch errors at
runtime, even if you recompile everything. The worst case is that you'll
get data corruption errors that cause incorrect results without actually
causing any exceptions. Basically the same story as we used to have with
CALL + PARM, where there was no validation even possible.
