RE: iSeries and PDA

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
