iPad emulation shows off app's fine-tuning
An IT director whose 3000 application runs on fine-tuned screens has sparked an upgrade in the iPad terminal emulator TTerm Pro. Jeff Elmer reports that his specially-coded VPlus fields have made the transition to the iPad application. All it took was an enhancement request, he says.
At Dairylea Cooperative, a group of milk producers based in New York State, the company has employed HP 3000s for more than three decades. The application uses the ability to map colors to fields -- a feature of WRQ's Reflection -- to guide users through inquiries, deletes, changes and adds.
Color-coding fields is a classic HP 3000 nuance, one that permits data entry workers to keep pace with the efficiency and speed of the HP 3000. Elmer's story reminds me of a report from the IT manager for the Oakland A's baseball team. When asked in the 1990s if his staff was ready to switch to a Windows-based interface instead of traditional VPlus forms, he said, "If I did switch them, they'd have me hanging from the flagpole in centerfield." User practices -- okay, habits -- have a way of producing efficiency. If the iPads at the Cooperative were going to replace some terminals, they'd have to stop blinking, even if the colors won't map across.
Historically we used the enhancement characteristics of the fields in our VPlus screens in conjunction with Reflection’s color configuration to color code our program screens. That is, in “Inquiry” mode the fields were a light purple. In “Add” mode the fields were white. In “Change” mode the fields were yellow. In “Delete” mode the fields were red.
These visual cues were very effective in helping our users know exactly what they were doing to the record without having to think (and we all know that thinking is not popular). However, when it came time to test HP 3000 access via TTerm Pro on company iPads, we quickly discovered that several of those fields were constantly blinking and made an otherwise perfect solution unpopular.
In fairness to TTerm, of course those fields should be blinking, since the blink attribute was on in the forms file and TTerm doesn’t map to colors in the same way as Reflection. I sent an e-mail to Turbosoft's support asking if anything could be done. They responded quickly.
"Clearly Turbosoft understands customer service," Elmer reports. "They told me how to capture the information they needed to investigate further, and in short order rolled out a new version to the App Store with an On/Off control for blinking. They followed up with me immediately to see if the change met our needs. The screens are now perfectly readable with no 'end-user annoying' blink."
The $49.95 app is working to capture other 3000 specifics, too.
A very nice feature of TTerm Pro is HotSpots. This enabled us to put a softkey on-screen for the enter key and allowed us to set up automatic logins for specific users. The “enter key” looks like a function key label in the bottom center of the screen (between the other function keys) and the automatic login is an on-screen button labeled “Login” which appears instead of the MPE i/X prompt. Touch it and you log in. For our application on an iPad, this is probably as close to perfect as we’re going to get.
