[REBOL] Little questions, big answers...

From: dness:home at: 4-Sep-2001 15:48

Although I have considerable experience across a wide range of programming languages, REBOL is different enough that learning it is a challenge. So far it has been a very productive and worthwhile challenge, but `hard' nonetheless. I have a few small fragments of code that (a) work; and (b) I don't understand at all (having cribbed them from some piece or other of working code). I have the feeling that if I could gradually understand them, I'd learn something about REBOL. Here's an example. I have dex-pane1: layout/offset [ origin 0 space 2x0 across styles dex-styles label right "IP Address" 200x24 bold middle font-size 16 return IP-1: fld right return IP-2: fld right return IP-3: fld right return IP-4: fld right return IP-5: fld right return ] 0x0 which produces a panel in a display of IP addresses and Machine names. What I am unclear about is at least: (1) what _are_ `IP-1' ... here inside the layout. Are they `objects' created by this declaration? (2) Is there some way I can `dump' `IP-n' to take a look at what they are; (3) My display obviously is `wired' to display 5 addresses. How would one normally generalize this. Although detailed programming advice is always welcome, I am more looking for (a few) words about what is really `going on' in something like this `layout' declaration, if that can be answered in less than a long epistle.
