🙶 My apps look like real web apps, not converted green screens, which we can access via any browser. Having lots of RPG apps, limited HTML experience and the need to add new functionality, Presto was truly the way to go. 🙷

Q. What are the benefits of using Presto for IBM i green screen modernization?
Providing browser-based applications improves end user satisfaction and reduces training costs because the screens are more intuitive and simpler to navigate. End users only need a browser to access the applications making Presto-modernized applications easy to deploy and maintain. You can also give remote users access to the applications from desktops or mobile devices without requiring a 5250 emulator.
Presto extends the functionality of your programs by enabling you to use images and web interface components and allows you to repurpose them for vendors and clients. Read success stories to learn how our clients have benefited from Presto.
Q. Is there a trial version?
Presto includes a free, fully-functional 30-day trial – no credit card required. After the trial period, you can purchase an annual license-free subscription. A Presto subscription is a convenient, low-risk and low-cost way to get more from your investment in your existing systems right away. With a Presto subscription, you will have access to everything – the tool, new releases/enhancements, technical support.
Q. How long does it take to install Presto?
You can install Presto in less than 30 minutes and see immediate results. Presto includes a pre-configured instance of the Apache HTTP web server to make the installation as simple as possible.
Q. How long does it take to web-enable green screen applications with Presto?
The amount of time it takes depends on the quantity and type of customizations you want to make, if any. As soon as you install Presto, every screen on your IBM i is instantly accessible from a browser. This means that all of your programs, menus and system screens are automatically web enabled. Clients who want the out-of-the-box results can often go live within a week. You can optionally add images, links, drop downs and other more advanced functionality to suit your needs.
Q. Does Presto work with any version of RPG or COBOL? Do you need to change the source?
Presto works with programs created using any version of RPG or COBOL. There is no need to change any of your existing RPG, COBOL or DDS code. Presto doesn't even require DDS because it uses the 5250 datastream.
Q. Is System/36 supported?
Yes.
Q. Can I still run my original green screen application?
Yes - Presto doesn't affect the original 5250 green screen programs. You can continue to run them while you access the web enabled version.
Q. Are mobile devices supported?
You can access Presto screens from any mobile device. Presto includes a virtual function key keyboard and mobile layouts that can be customized for specific devices.
Q. Are system screens like Work with Output Queues and third-party applications supported?
Yes, all system and third-party screens are web enabled. You don't need the source to give screens a web GUI with Presto.
Q. What is the learning curve?
Presto's learning curve is short. It would take you days - not weeks - to become proficient at enhancing screens using the Presto Visual Editor. Being familiar with HTML, JavaScript and CSS can come in handy but is not required for most types of customizations you'll make. We have excellent documentation, examples and technical support to help you with web technologies.
Q. How does Presto affect system performance?
Your IBM i should perform the same whether you are running the Presto or the green screen version of your screens. You can run Presto in batch or interactively. Presto uses advanced web technologies like Ajax to render the screens as quickly as possible. While you can never beat the rendering speed of text-based screens, your users shouldn't notice a performance difference on most screens.
Q. What is the difference between Presto and WebSmart?
Presto web enables existing green screen applications while WebSmart ILE and WebSmart PHP are used to develop new web applications or to rewrite existing green screen applications. When web enabling an existing application with Presto, you don't touch the underlying RPG or DDS code. WebSmart PHP and WebSmart ILE use a template-based approach that gives you the ability to rapidly develop new web programs. You can reuse existing RPG code from both editions of WebSmart by calling back-end RPG programs, but you cannot automatically convert existing programs with WebSmart as you can with Presto.
