The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
As far as style is concerned, my only objection would be the use of the #
character as a variable prefix. But I understand that each shop has their
own naming conventions, and I don't expect others to have the same as mine.
As far as structure is concerned, it's well formed; much better than a lot
of alternatives.
Regarding performance, we're talking very few microseconds to evaluate a
"when" condition. Contrast that with most web application environments
which "route" browser requests to appropriate "servers", whether they be
Java servlets, or scripts running under interpreted environments, you will
find a comparatively HUGE amount of overhead in the latter.
Your structure for dispatching requests based on #WrkMode could be viewed
as the "controller", following a Model/View/Controller design pattern. Bind
your controller to a *SRVPGM which implements procedures to handle screen
I/O, then bind that *SRVPGM to another *SRVPGM which implements database
I/O. Now you have an application that implements a very maintainable MVC
design pattern.
