CHUI - piecemeal upgrade?

Hi all,

We have an in-house Progress 8.3b system with character (CHUI) clients running

on PCs with terminal emulators, and UNIX dumb terminals. The system has evolved

over a number of years, and runs on UNIX.

The system currently supports English only - and we would like to internationalize

it. My current thoughts are:

- Upgrade to version 9

- Convert database to UNICODE

Question 1:

Am I right in thinking that although CHUI clients donÂ’t support UNICODE, the

CHUI clients should continue to operate OK so long as ‘strange’ characters

arenÂ’t used in the database? (In other words, converting an English DB to UNICODE

should cause no problems for the CHUI client?).

Question 2:

Eventually the clients will have to be changed to GUI/Web to provide richer

functions. I am thinking of upgrading parts/functions of the CHUI system to

use AppServer and GUI/Web clients function by function. This would mean the

users would access some screens using the old CHUI, and others using the new

GUI/web client with AppServer. SoÂ…

- Is this possible?

- Does anyone know of a method to integrate the old CHUI and the new GUI/web

functions into a single interface, to save users switching between 2 apps?

The goal is that over time all the functions of the system will be moved from

CHUI to GUI/web with AppServer, meaning we have achieved a piecemeal upgrade.

Thanks in advance!
