sqlab
Sorry that was wrong (:
sqlab
keep/only does the trick
out: collect [
    parse In [ some [
        [copy str string! copy bl block!  (keep  str keep  bl)]
        | [copy str string! (keep  str keep/only  []) ]
        | [copy bl block! (keep   "" keep bl) ]
        |  skip
    ]   ]
]
== ["" [upper] "key 1" [] "key-2" [no] "" [off] "key 1" []]

That looks good, sqlab -- thanks!
One minor change:   keep/only  []   ===> keep/only  COPY []
Then each inserted empty block is a different one (which wasn't explicitly stated in the puzzle description; but it helps the actual app).
Ditto (keep COPY "" keep bl)

I constantly forget about COLLECT and KEEP, and everytime I say "cool!" when I see them :)

This might not be the best place to ask this but since it directly involves learning it seems as good a place as any. I'm wondering what books any of you might deem essential for programming and systems architecture. Do any of you have a favorite book on system architecture?

On Software Architecture
- Beautiful Atchitecture is real world stories, but not all will teach you something. Overall I like it.
- Software Architecture in Practice is dry and rigid. I don't like it.
- Software Architecture and Design (Witt, Baker) is pretty good, if somewhat dated
- Software Architecture (perspectives on an emerging discipline) (Shaw, Garlan) I like, as it's not huge and their views align with mine. :-)
- Beyond Software Architecture didn't grab me. Lots of business related stuff in it.
- Domain Driven Design is good, as it applies to DSLs and such.
On programming, are you looking for coding specific stuff (e.g. Programming Pearls, Code Complete) or more general (Making Software, Rapid Development)?

I'm looking to improve the way I structure my code so that it's both more readable and easier to maintain.
Geomol
Books I often use in combination with programming/development/language design:
- The C Programming Language (Kernighan and Ritchie).
    Most out of need, as I program in C also. Wish I didn't have to.
- Object-oriented Software Construction (Bertrand Meyer)
    Many very good ideas, even for outside real object-oriented languages.
- Programming Languages: Design and Implementation (Terrence W. Pratt)
    Cover lots of languages and designs.
- Data Structures and Algorithm Analysis (Mark Allen Weiss)
    The data structures ABC.
- Amiga ROM Kernel Reference Manual, Libraries & Devices
    Yeah, it actually still has useful stuff, even if it is old.
Carl's Style Guide has good tips for readability:
http://www.rebol.com/docs/core23/rebolcore-5.html#section-5
I changed my way of writing code, after I looked at the sources for Lua. Now I tend to write condenced code without empty lines, and then have two empty lines between functions.
And putting brackets on the same line as function definition, and space before parenthesis:
    void my_function (arg1, arg2) {
        ...
    }
Same with IF, WHILE, etc in REBOL:
    if something [
        do this
    ]
    while [this-is-true] [
        do this
    ]

That's how I format my code as well but I'm looking for something more along the lines of naming convention dos and don'ts. And how to create useful objects in OO programming.
Geomol
On naming, Carl has the best suggestions, as I see it:
5.2 Word Names
5.2.1 Use the Shortest Word that Communicates the Meaning
5.2.2 Use Whole Words Where Possible
5.2.3 Hyphenate Multiple Word Names
5.2.4 Begin Function Names with a Verb
5.2.5 Begin Data Words with Nouns
5.2.6 Use Standard Names
CelesteM
That looks like an excellent list right there.
Geomol
I don't do much OO programming, because it is so hard to find useful objects. :)
If I was to create a game, I would make a character object (the character, you play), objects for objects in your surroundings, etc. That is easy, because it relaty to the real world.
If I should write code, which would sort filenames in a directory, I would write a function, not use OO.
CelesteM
But in reality, each file is a separate object...
Geomol
I can only recommend reading Bertrand Meyer, if you wanna do OO (and even if you don't do OO). And I don't program in Eiffel, which is used in his book. He just have many real good ideas.
