World: r3wp

Well, post it as a wish then. I haven't needed it, and I'm concerned 
that the dual meaning of ANY in the context of PARSE might be confusing, 
but Carl has the final say.

must not be 'any, its just what is now used inside the dialect. maybe 
parse/many ?

Most scripting languages (like Ruby) and even some programming languages 
(like Java) support the string-concatenation operator "+".

>> "a" + "b" 
== "ab"


I know that we can use the JOIN function, but a + operator for string 
would be nice too. Why doesn't REBOL do so?

>> "a" + 2 + "b"
** Script Error: Cannot use add on string! value
** Near: "a" + 2 + "b"

>> rejoin ["a" 2 "b"]
== "a2b"

What could be more elegant ?

:) (and reads well to).

Yes, I find all those interspersed concatenation operators tiresome 
and ugly.

'rejoin' sounds like it was already joined once

uhuh.

If I knew nothing if programming languages, I would think "a" + "b" 
= "c"   ;-)

when I first met programming language - basic on 8 bit home computer, 
I could not get how A = A + 1 can be valid :-)

to try to patch ubuntu REBOL/Core today for serial ports, I did:
reb-orig: read/binary %rebol
replace/case reb-orig "ttyC0" "ttyc0"
write/binary %rebol-patched reb-orig


...but when I try to run the patched binary it gives some crazy line 
errors.   I differenced the two executibles in REBOL and got some 
crazy differences more than just what I thought I was changing.

(2 of my computers died, so I don't have the hex-edit.r of Ryans...so 
was seeing if I could just patch the binary with REBOL itself.   
Perhaps the replace by strings did some inherent conversion of the 
REBOL executible...not sure.

you might want to count how many there are first?  if only a few, 
maybe replacing one at a time will end up working?

I think there is a way to specify your serial ports. I don't remember 
how. I but I have done it the past. I should search my files.

If anyone has hex-edit.r and could post to library...or link...it 
would be appreciated.  I didn't plan to have my computers down.  
It is IOS/Developer/Users/Ryan-Cole/Utilities ... IIRC

Have you tried this?

append System/ports/serial 'ttyc0

port: open serial://port3/9600/8/none/1

This way you don't need to modify the binary et all.

Hi Jerry, "I know that we can use the JOIN function, but a + operator 
for string would be nice too. Why doesn't REBOL do so?"


Do you think it would be nice because it's more readable, or because 
it's familiar to people coming from languages that have it?


I came to REBOL with a long BASIC history, and it didn't take me 
long before I didn't miss + for concatenation at all. + is really 
a math op; I like REBOL's consistency, and I like the way REBOL concat 
code reads.

Jaime...thanks, but I get the same error ... Access Error:  cannot 
open ttyc0

ttyc0 is actually there, and ttyC0 is not (in the /dev directory) 
and I have tried root  and normal passwords.

but I am running AltME on ubuntu now.

did you try with ttyc1 etc as well? ttys0?

Why won't you just copy ttyc0 to ttyC0 so you will have both versions?

Never mind. That doesn't seem to work.

Try this:

system/ports/serial: [ttyS1]

port: open serial://port1/9600

Steve, Regarding "access error" are you sure you have enough user 
rights?

I tried logged on as root and as normal user, both give the same 
error.

Edgar...that WORKED!...yahoo!

still need to test with the devices...(so how did you ever figure 
that out?

Search the net for normal C-serial port access.

Linux uses ttySx and Cygwin uses comx.

now the whole controller can be done in REBOL.

Are you from Italy?

No, I am from LA.

you city's name can be juggled to "Legs On Sale"

I was experimenting with CoLinux. Got tired of DualBoot.

Actually my City is Norwalk but LA is more known.

well, thank you very much...this is very exciting.  I had tried ttys0 
but never thought to try ttyS0, since in /dev it is ttys0

Hi, I need some help with BIND (I think that's what I need to use): 
I have a storage context, that has a bunch of function to handle 
the storage of other contexts. That those storage functions can work, 
they need to have access to the other context. I could do:
storage/save-record context-to-save ...

but I would like to do: context-to-save/save-record.

and avoid dubplicating the storage code in every context, or write 
stub-functions that reference the storage stuff.

Is it possible to bind the storage functions dynamically to the context 
that should be saved and switch this binding in the app depending 
on which context should be stored?

In other languages this is called delegates (IIRC).

Example:
context A [a: 1 b: 2 c:3 list-words: none]
context storage [list-words: does [probe first self]]

How can I execute storage/list-words in the context of A? So that 
I get back [a b c list-words]

I think I need to switch the way it works:
	do bind [first object] storage
