You have to tell what are you comparing with what.

i am comparing values of two tables
Ladislav

Yes, but you obtained your RESULT. Now, you are processing the RESULT 
block, I assume?

i want to say if they are same print otherwise alert to user
yes
correct
Ladislav

[1546x3]
So, you are doing something like:

foreach record results [
    if first record = second record [...]
]
Is that it?
correcting myself:

foreach record results [
    if (first record) = (second record) [...]
]

is correct or no ...should i use alert?

This is more likely the code you might use:

foreach record results [

    either (first record) = (second record) [print ["they are equal:" 
    first record]] [print ["Alert!"]]
]
ALERT is not meant for CGI, it is a GUI function.
afsanehsamim

[1552x5]
yes
what are you suggesting in GUI?
sorry
CGI
?
Ladislav

[1557x2]
So, no, if you are creating a CGI script, don't use ALERT
For CGI? I do not know, how about some blinking text, or red text, 
or, I do not know what people use...

I execute the following line and capture the HTTP packets using Capsa 
(or wireshark) I don't see any header information in the packets 
sent:
read/custom http://moldibi.com[header "X-hello:1"]


but when I run curl with same parameters, I can see the extra header 
information,
curl http://moldibi.com-H "X-hello:1"


does it mean I cannot add extra header information using REBOL or 
am I doing something wrong? (I'm using R2/View)

Use the 'header directive :)
oh .. you are!
http://www.compkarori.co.nz:8000/Protocols/Http

 read URL [ header [ Cookie: "authtoken=anotherfoo" ]]
Header expects a block
Endo

in default HTTP protocol or your version?

default http

oh yes!!! now I can see when trace/net on.
Thanks a lot!! Tomorrow I'll try with salesforce, I hope this is 
the only problem.
It's not written in any where in the REBOL documents. Even in Core 
PDF.

from my page "NB: Rebol2's existing prot-http currently supports 
this undocumented method using a 'header keyword"  :)
I think Gabriele mentioned this many years ago on the mailing list
That's why it is so frustrating having static documents .. that only 
one person can change. Wiki is better.

That's right. I read your page now. Thanks a lot, it will save my 
day.

Endo,  a lot of stuff in rebol is learned by scanning the source 
code... and probing or using help on system and its members.


you can probe all the port handlers to see how they work, I still 
do this all the time... most of the very skilled Rebolers know , 
above all else, how to browse the rebol source included in the interpreter 
itself.

Finally I got it work with Salesforce, when I complete my work, I'll 
write a document for it, so I can save someone's hours.

I was asked for examples of the DRAW, I used to create the graphi
graphi
graphics in GCam.

The start of a button is:
img: make image! 88x88
img/alpha: 255

draw img [
	pen none
	fill-pen linear 0x0 0.0 88.0 90.0 1.0 1.0
