The main advantage of a screen wrapper is obvious. You can put a good looking, easy to use, high GUI veneer over 5250 screens, without having to spend the time and money required to analyze, rewrite and then retest all the business logic imbedded inside them as you would if you replaced them with VL components.
This is especially important for users to whom platform portability is of no real interest because they are content with a IBM i only solution.
Usage Examples
Some usage examples might include:
...
- 85% - 5250 screens – to get to market ASAP.
- 10% - screen wrappers - to rapidly replace some heavily used and critical areas (eg: Order Entry) with something much better to use that adds a lot of business value.
- 5% - VL components – add high end value to the application (eg: E-Mail, PDF documents, MS-Excel spreadsheets, Web integration, etc).
