RE: iSeries and PDA

Arco, don't apologize for your English, it is fine.
One thing I suggest you do, before you head down this road check out how
your app will look on the smaller PDA screen.  The Mocha emulator does allow
you to control the font (to some extend), but using a larger font may not
show the entire screen.  In order to use the application, you may need to
modify your screens so the entire display is visible without the need for
the user to "window" from left to right or up and down.  If you go the Palm
OS route, be sure to get a device that supports the hi-res version of
mochasoft.  My Treo650 does, but my Treo600 did not, and the hi-res screen
makes it so much more readable with the smaller fonts.

Hi Walden,

What we want is to make some RPG applications available to a PDA, and I'm
sure that amount will grow if it works good.
It looks like it can be done very well by using Mocha's TN5250. We want to
connect through GPRS. 
If I understand right, Mocha will use very little bandwith, and it seems to
cause very few network traffic if there is no activity of the application.
If that conditions are met, I think using Mocha over GPRS will offer us all
we need whithout recoding those apps.

I wrote "programming environment" but by that I meant "development
environment", English is not my natural language, sorry.
I'm not experienced with C# and I don't like to go learning now with a new
development suite like Visual Studio.
Especially not if I can get the job done by tools that are written for our
platform, for example if I would migrate apps to a browser environment I
could use CGIDEV2. (however I doubt when I see the latest issues with
Easy400) It is not that I refuse to learn something new, but we are a small
company and a mix of different programming languages will make it more
difficult to maintain. So I have to make choices for this moment. Maybe .NET
comes in later.

Best regards,
Arco Simonse
