Gregg has posted a dialected substring function.

rebol's help also should have a see also at the bottom of commands, 
to direct attention to other rebol commands and functions of interest

the language as a whole feels very fragmented, I recognize the power 
of Rebol only because of its lispy nature, but I feel limited compared 
to a language like perl, because examples are far too scattered about, 
and the names for functions are often oddly named or sometimes the 
functionality exists but is so obscured that I never knew it was 
there at all in the first place

I hope more is done to actually document the language when 3.0 rolls 
out

and sure perl ain't the prettiest languages on earth, but it is well 
documented

for example, how could I take a date, and add 3 months or 3 weeks 
to the date?

a CPAN for Rebol?

hmm, that is one idea, hehe

But I am actually talking thorough discussion and documentation of 
every nook and cranny and how to do basic things people want and 
need to do with the language

something along the lines of the rebol core manual, but more in depth

having to re-invent the functionality that other languages just give 
you is a serious pitfall if you ask me

that was one of the things that drove me crazy about lisp, yeah it 
is a powerful language, and yeah it is a programmable language, but 
to some degree the only way to do anything really useful in the langauge 
was to in essence program lisp to function similar to other languages 
you were already familiar with, or to in essence extend lisp with 
functionality it should have already had before you even started 
programming in it it

in some ways this might be considered an elitist atttitude on the 
part of the language writers.

If it's not there, write it yourself.

Better to have a way to point to mezzanines that implement the common 
functionality that people want.

I dunno, I think that languages like java or .NET would be far less 
successful if people had to implement a majority of the class library 
by hand, anytime they wanted to take advantage of advanced functionality. 
There is just some functionality that people come to expect regardless 
of what higher level language they are coding in. And for a language 
that supposedly can be used to parse and manipulate text and data, 
not having a built in substring function is pretty crazy

Rambo your suggestion.

that is my primary need or want to use rebol for, is to manipulate 
text. I like perl, but  love rebol's small footprint, if it can give 
me the same power of perl in a much smaller package, with a gui, 
that is all the better. I could potentially replace access and a 
lot of proprietary tools with a small rebol view application.

I like how rebol handles tagged data, xml, html, etc.

I am surprised save can't serialize rebol datastructures in xml formats

I dunno maybe I am being anal, or stupid, or just plain unreasonable. 
But this sort of irked me, when I found people offering a solution, 
and it was so simple as to have just been a part of the darn language 
from the beginning.

I hope more documentation on view itself also debuts

actually it was Jaime

substring: func [
    [catch]
    source [string!]
    spec [block!]
    /local start stop rule
][
    rule: [set start integer! '.. set stop integer!]
    unless parse spec rule [
        throw make error! "Invalid range spec."
    ]
    copy/part skip source start stop
]

this was in my response to my suggestion that we adopt a python type 
syntax for parts of series

substring "abcd" [2 .. 3]

so skip is skipping into the string, then it is copying part of that 
string starting from that position to the end?

Oddly enough, *I've* never needed substring type functionality in 
REBOL. Might be due to the fact that REBOL's multitude of datatypes 
reduces the need somewhat (i.e. in another language you may have 
to manipulate numbers / strings to / from dollar / date / time formats, 
whereas in REBOL I tend to convert via the to-* functions).

well, one thing I've wondered is how to add weeks, months, years, 
etc. to dates

Jarod - yes.

I like that function a bit more Graham, I basically think I understand 
what that is doig

the ".." is synatactic sugar.

doing

having to write a function to do that is a pain, but I can probably 
live with it, knowing exactly what it is doing

I mean, all languages have quirks

hehe

I don't use substr much at all either .. but your complaint was one 
I also felt :)

I mean, there are times when parse will work

but honestly, I could actually see parse having the ability to substring

I am surprised it doesn't

how can you do more with dates than just add days to them?

So why doesn't someone write a .r file you can run that adds common 
functions for other languages (i.e. basic.r would have 'substr,

I guess there are several ways it could be implemented

user.r ?

putting it in user.r?

Someone (or a group of someones) should write a .r file for the common 
languages (i.e. basic.r would include 'substr, 'peek, 'poke, etc.; 
rexx.r would include 'mid, etc.).  That way, new users from other 
languages could move into Rebol with the knowledge they already have. 
 Of course, the script flow would be different, but their favorite 
functions would be available, and they could see how to implement 
their favorite functions natively using 'source.  There could also 
be a %c.r for those coming straight from C. :-)

and things like .. cd, dir and other common dos functions

Ah, but to implement dos.r, you would have to remove about 90% of 
Rebol's functionality ;-)

Just kidding...I was being mean about how bad DOS really is as a 
scripting language. :-)

Jarod...I guess you are asking about how to add to dates.  Here is 
an example:

>> b: now/date
== 27-Mar-2006
>> b/month: b/month + 6
== 9
>> b
== 27-Sep-2006

that adds months, what about weeks?
