Have I written text-based programs for PC: yes. DDS is definitely easier, there is no question. But AS/400 programming is more akin to modern visual programming, because it uses form-based displays rather than those built character-by-character. If you look at (say) Visual Basic,* I can code a list display by dropping a ListBox onto the form. Adding items to the list is done using lstCustomers.AddItem. Positioning the list is equally simple: lstCustomers.Item(n).EnsureVisible. And so on. Positioning the cursor to a text field: txtUnitPrice.SetFocus. To protect a field: txtUnitPrice.Enabled = False. Compared to character-based screen coding, display files are a huge improvement. But they still leave _way_ too much work to do. ____________ Paul Cunnane The Learning Company * Disclaimer: I'm not saying that VB is in any way comparable to RPG in terms of quality, just pointing out the way things can be done, when there is a will...! ______________________________ Reply Separator _________________________________ Subject: Re: "extract" command enhancement(subfiles and BIFs) Author: "Scott Klement" <infosys@klements.com> at InterNet Date: 22-09-99 10:12 am Wow. Okay, maybe I'm nuts (yes, I probably am nuts, and will probably get a few replies telling me so) but I always thought display files were a very easy and convienient way to do plain-text screens. Have you ever tried to write programs with display-file-like functionality on PCs? or for UNIX machines? - snip - +--- | This is the RPG/400 Mailing List! | To submit a new message, send your mail to RPG400-L@midrange.com. | To subscribe to this list send email to RPG400-L-SUB@midrange.com. | To unsubscribe from this list send email to RPG400-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +---
