RE: D-Specs for Java Prototypes in RPG

That makes a ton of sense.

Thanks to both of you who responded.  Just needed my head screwed on correctly.

Subject: RE: D-Specs for Java Prototypes in RPG

In any prototype, the "type" field to the right of the PR says 
whether<br>anything is returned.  It could be any type, including integer or 
alpha, or,<br>in this case an object (type "O").  Notice that the prototype for 
pkgMethod<br>doesn't have a type of "O" in the prototype line.<br><br>If this 
is truly a void method, just remove the "O" from the prototype line.<br><br>As 
to returning a boolean primitive (little b), simply code the return type<br>as 
"N" (indicator).  For more on this, check
