Re: Green-screen versus browser

Good points, Doug.  A keyboard is going to be more
efficient than a mouse for data entry in most cases. 
Part of the effiency though is in downloading an
entire score sheet to the browser, then submitting it
to the server as a batch, as opposed to requesting
server resources for each event triggered by the UI,
such as changing the input format, popup windows, or
paging.

These particular scores are recorded by teachers, not
data entry clerks, and done just three (3) times each
year.

For those who may not know me, I'm not suggesting
offloading Web applications to .Net or J2EE runtime
environments.  Nearly everything I do is in ILE RPG.
