Re: New parameter needed for a subprocedure

I too agree with Kurt and Scott, at the same time I prefer the use of and do
use return parameters more. There are some cases when it just makes more
sense to use the output parameters.

A good example I think would be reading an IFS file.

fd = openFile('/somedir/somefile.txt');
dow (readFile(fd : %addr(string) : %len(string)) > 0);
// do something with the string
enddo;

It make more sense to me to have the return value pass back the buffer
length rather than the string. Passing back the string, how would you know
then the file is complete? You could pass back a blank or an arbitrary
string, but 0 is always 0.

Just my opinion though.
