Hi all,
I have a layout with a load of entry fields (VID style Field). I need to
occassionaly display this with all entry fields disabled.
So (I think) I need a way of running through the layout and changing all
'field style faces to 'info style (and vice versa to make it enterable again).

Here's a simple idea, and a simple script to go with it.
With View, you are either running your Layouts, and
wondering why Things Aren't Right, or you've stopped
the application and are Printing away at the console
to see what's up.
So why not have a debug window that lets you type
commands as

adding some other issues about contexts).

Hi all.
Romano, in his response to me about strings and blocks reminded me of some
pain I'd had trying to use 'load as a validation tool.
Can I lay out what I see as then problems, and maybe the gurus can tell me
what I'm missing? Thanks

Hi all,
It may just be my irredeemably old-fashioned mindset,
but everywhere I turn in Rebol I see the need to 'DO strings.
I've been ticked off before on the list about it and -- these
days -- I can normally see better approaches.
But this little example has got me stumped. So I'm interested

Both "The Official Guide" and "Rebol for Dummies" have short sections on
this...and they are both worth having for other reasons too.

I had a similar problem last week. My script ran fine if browsed from
Internet Explorer or Opera. But it downloaded as a text file if browsed from
Lynx.
I spent a long-time banging my head against a click wall trying to fix it. In
the end I put it to one side. Strange thing is, Lynx works fine

Thanks! Not quite, but enough of a clue to find something that does do what I
want.
Your top-level? means "Am I being typed at the Command Prompt?"

Thanks to everyone who replied to this. I've adopted Scott's approach.
I guess my problem was twofold: expecting FIND to do more than it does; and
being unable to fathom SORT.

That touches precisely on something I was trying to figger out the other day.

Can you guys help me on this one?
I've got a structure like this:
MyStructure: [ [key1 data1] [key2 data2] [key3 data3] ... ]
where each Key is a single string, but the Data is another block.

Is there any way in Rebol that I can extend the number of significant digits
when doing arithmetic?
I'm trying (as a Rebol-learning exercise) to convert some old Rexx code. In
Rexx, the problem is trivial:
/* rexx */
a = 11
b = 71
say " default=" a / b
numeric digits 25
say " 25 digi
