parse blk [some [s: set value integer! (if value = 23 [print index? 
s])]]

not sure my version will be the smartest solution, but you can try 
how fast it is :-)

indices?-1: func [
	series [series!]
	value
	/local result
] [
	result: make series 0
	while [series: find series value] [
		append result index? series
		series: next series
	]
	result
]

indices?-2: func [
	series [series!]
	value
	/local result
] [
	result: make series 0
	parse series [

  any [1 1 value series: (append result subtract index? series 1) | 
  skip]
	]
	result
]
>> time-block [indices?-1 blk 23] 0,05
== 0.000006591796875

>> time-block [indices?-2 blk 23] 0,05
== 0.000005645751953125

(in R3)

Could you rewrite my example as indices-3? :-)

How about Rebol 2 version?

pekr, your example will be slower

since your comparison is occuring in a mezzainine

what mezzanine?

Lad, it works in R2 as well.

if value = 23

but Ladislav is doing this 

1 1 23

yes, that (in R3) means, that the times obtained are in R3

where do I get time-block from for R3?

where do I get time-block from for R3?

Write:

do http://www.fm.tul.cz/~ladislav/rebol/timblk.r

hmm, what does this mean? Is it intended? In R3:

>> exists? http://www.fm.tul.cz/~ladislav/rebol/timblk.r
== none

Hmm, my version is much slower:

indices?-3: func [
        series [block!]
        value  [integer!] 
        /local result
][
        result: make series 0
        parse series [

               any [s: set wanted integer! (if value = wanted [append result index? 
               s])]
        ]
        result
]


>> time-block [indices?-1 blk 23] 0,05
== 0.000004669189453125

>> time-block [indices?-2 blk 23] 0,05
== 0.0000039520263671875

>> time-block [indices?-3 blk 23] 0,05
== 0.0000059661865234375

what is this dirty trick good for? :-)

1 1 value ???

It's because you can't match an integer like a word

looks like foreach is still the winner (on r2)

Against a block with 100,000 integers

Lad's : 0.047
foreach: 0.044

Terry, you did not write the Foreach-base algo here, so nobody can 
compare...

1 1 value means to run the rule once and only once where value is 
the rule

A bit adapted Lad's version (does not use substraction):

indices?-4: func [
	series [series!]
	value
	/local result
] [
	result: make series 0
	parse series [
		any [series: 1 1 value (append result index? series) | skip]
	]
	result
]


>> time-block [indices?-2 blk 23] 0,05
== 0.000003936767578125

>> time-block [indices?-4 blk 23] 0,05
== 0.000003753662109375

interesting, I thought, that this modification would be slower

(index?-2 spares four assignments, while index?-4 spares two subtract 
calls)

what are your results compared to foreach?

gotta go.. bedtime in the pacific northwest

Is there any other way of how to put word in, instead of 1 1 value? 
Quote? Hmm, probably not ... I don't like the form ....

if we have 'set, we could have 'get, no?

Replacing "1 1 value" by "quote (value)" as variant 5:

indices?-5: func [
	series [series!]
	value
	/local result
] [
	result: make series 0
	parse series [

  any [series: quote (value) (append result index? series) | skip]
	]
	result
]

>> time-block [indices?-1 blk 23] 0,05
== 0.0000047607421875

>> time-block [indices?-2 blk 23] 0,05
== 0.000003936767578125

>> time-block [indices?-3 blk 23] 0,05

== 0.000003692626953125

Nice .. we don't have quote in r2

Wonder if that could be back ported to r2 ...

Matrix - There is no spoon ...
REBOL - There is no R2 ....

... forget R2 :-)

Brian will object anyway ...

I think that backporting parse, which is totally rewritten for R3, 
is really meaningless waste of energy ...

except for those of us using R2

Remember that we are paying R2 customers .. and R3 is not going to 
be usable for a few more years

If you would not use GUI, what exactly would be holding you back? 
You created even basic networking schemes? As for me, I miss fixed 
'call - it is still hugely crippled and absolutly useless ...

I don't do any non gui apps

Graham - that is nonsense, no? I mean - not being usable for few 
more years ... but we should move the discussion to R3, or advocacy 
...

Pekr, it's still alpha!

It took 4 years to reach alpha

e.g. for me, RebGUI is a dead end. I talked to Bobik, and he is back 
to VID for simple stuff. There were many changes lately, and some 
things got broken, and it does not seem to be supported anymore. 
As for GUI, I believe that in 2-3 months, you will be able to talk 
otherwise, as Robert wants to move his tools to R3 definitely ...

I don't care about the stickers. Someone said it is alpha, so tell 
to your brain, that it is a beta, and you are OK, easy as that :-) 
I use products according to functionality, not its official alpha/beta/theta 
status ...

I used Mozilla since 0.96 and it worked for me :-)

sorry, it's still alpha quality

Henrik: ahttp works basically like async:// - there are no docs other 
than the Detective sources.

Cheyenne is R2. I need something that works with it.
