Re: Cases in AS400

Chapin,

 I must disagree.  Since you can't directly debug an action diagram, how 
would you track down a difficult to find bug?  The only practical way is to 
go into the generated code.

 As an example I have worked with Progen.  It generates very decent 
code.  It is even documented!  The options you have are fully documented or 
VERY fully documented.  There is no reason that code generators can't 
generate decent, human readable code.
