Re[2]: "extract" command enhancement (subfiles and BIFs)

     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.

     when there is a will...!

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?
