>So if I'm writing a piddly app from a UML specification, should I be creating a full-blown class-driven app that takes a month, or quickly knock up a one-off app that may take a week??? And require no more attention

With time, it has become more difficult for me to write only procedural vs class-driven code ...

o1 = CREATEOBJECT( "MyApp" )
o1.Run()

DEFINE CLASS MyApp AS Session
..
PROCEDURE Run
..
ENDDEFINE
