I am speculating that the author intended this as a quick way of 
testing a script, just as I happened to write the exact same code 
in my script.
Steve , you are joking!!!

I asked on R3 chat and got this answer:


Re #3821: T won't make it to the final distribution - it's for the 
test phase.
It's not even documented. I expect that the function 
will go away inn the code
reorganization.

I have one question ... I have parse blocks stored in some external 
block:  parsers: [  aaa [ ( variable + 1 ) to abc ] ]  so I do select 
parsers 'aaaa to get that block .. and then I >>parse string get-parse-bock<< 
 


The problem is that "variable" in that block is defined in the function 
where parse happens ... and it's undefined inside parse block in 
this case ... any ideas how to bind it to it's outer variable... 
I haven't used bind or use before but I thought I can do something 
like this with bind .. but I can't make it work and I also don't 
"get" the bind example in docs
hm.. it seems I was using the parameters reverse and bind is exactly 
for this :)
...
I don't get this example:
    >> words: [a b c]
    >> fun: func [a b c][print bind words 'a]
    >> fun 1 2 3
    1 2 3

You give it just 'a to bind but is seems to bind b and c too??

yes, because they exist in the same context.
Janko
12-Jun-2009
[2818]
so it binds all the words from the context of the word you give it 
to?
Henrik
12-Jun-2009
[2819]
I think it's more correctly to say, it binds the context in which 
the words happen to exist.
Janko
12-Jun-2009
[2820x3]
yes, that is more clear way to put it
now that I know and read the docs I get that this is written , but 
I haven't before
thanks Henrik!

Asking for help on a formatting problem


I have the following block that cotains some rebol code which I wish 
to print  on the console and then execute the code:
>> code-blk: [print "ok"]          
== [print "ok"]              <-- assigned a code block just fine
>> do code-blk
== ok                            <-- looks good so far 
>> print code-blk

== ok                           <-- Nope that isn't what I was looking 
for, but I understand why since it is like print the results of print 
"ok"
>> print form code-blk

== print ok                  <-- getting closer to what I desire, 
but the quotes are missing
>> print mold form code-blk

== "print ok"               <-- not what I desired   -- I want the 
original code block to be printed as   print "ok" with the quotes

Any ideas on how to fix this?

PatrickP61

>> source code-blk

code-blk: [print "ok"]        <-- My goal is to just get     print 
"ok"    


Another way to pose the question is    How can I convert the entire 
contents of a block, including spaces, into a string?

have a look at source source

Ahhh, you are right Graham, since SOURCE did print the correct string 
somehow!  Will dig into it

[print "ok"]

print "ok"

Thank you ChristianE  -- I found similar code in SOURCE SOURCE

As always, there's a refinement you don't think of
 - that's the best thing to remember about REBOL :)

Excuse me. How can I get zero padded with numeric values?  for example 
I want the numeric strings  from "0001"  to "9999"

Several people have written such a function. Here's one of them:

Here's a QAD I use:

>> i: 1
== 1
>> join skip "0000" length? form i i
== "0001"
Graham

[2839x4]
next form 10000 + now/month
== "0008"
and for that mailing list question ... on how to format yyyymmdd


rejoin  [ now/year next form 100 + now/month next form 100 + now/day 
]
== "20090806"
now/year * 100 + now/month * 100 + now/day
== 20090806

guess have to benchmark to see which is fastest
last version is 5x faster

Doesn't measure that much faster here, and you have to add the FORM 
call as well. Still nice. :-)


If performance is important, you can do two things: 1) cache NOW, 
2) cache the whole result once a day.

I ran 10,000 iterations with 'form and found it was 5x faster :)
It's something I learned from Forth .. math is always faster than 
logic.
BTW, you can use the same trick for those pesky apis that want leading 
zeros for time

>> time: now/time - 5:00
== 6:29:02
>> next form 100:00 + time
== "06:29:02"

I am trying to retrieve email from a godaddy account. Their server 
however uses a username with the @ sign. I am not sure but I think 
this is messing up the pop protocol. 

The error I receive is:

connecting to: companyname.com
** Access Error: Cannot connect to companyname.com
** Where: open-proto



Notice that my pop statment has two @ signs in it but is needed to 
login to goDaddy's multi-tenent pop server.


foreach message read pop://[user-:-companyname-:-com]:[password-:-pop-:-secureserver-:-net] 
[
    print message
]

Any Suggestions?
