It would mean that doing a refactor and changing a method's name, or even adding a new parameter to a method, would break the code in some unrelated method. That's a huge maintenance problem.
Well, I took the OP to mean just the opposite. Procedures often have to be broken into two parts, esp. because of sheets; so, you might start out in doMyThing:, but then you show a sheet and after the delegate callback you want to proceed to doMyThingPart2:. Since the latter name is derivable from the former, passing _cmd is a sensible way to generalize this situation, and it's the exact opposite of a huge maintenance problem; provided the naming convention is obeyed (a common enough pattern in Cocoa), pairs of methods can be introduced or removed at will as development proceeds. m. -- matt neuburg, phd = m...@tidbits.com, <http://www.tidbits.com/matt/> A fool + a tool + an autorelease pool = cool!
