To get round that, "PROBE FIRST object" can be used, though it's not as verbose with
the info you get back. Examples...
>> help system
SYSTEM is an object of value:
version tuple! 1.2.46.3.1
build date! 6-Apr-2004/8:27:12-7:00
product word! View
core tuple! 2.6.0
components block! length: 48
words object! [unset! error! datatype! context! native! action! ...
license string! {REBOL End User License Agreement IMPORTANT. READ ...
options object! [home script path boot args do-arg link-url server...
user object! [name email home words]
script object! [title header parent path args words]
etc...
whereas PROBE FIRST gives you...
>> probe first system
[self version build product core components words license options user script console
ports network schemes error standard view stats locale user-license]
To check the type of any of those you can use PROBE TYPE?...
>> probe type? system/version
tuple!
== tuple!
>> probe type? system/words
object!
== object!
And to get their values, just use PROBE...
>> probe system/version
1.2.46.3.1
== 1.2.46.3.1
Or if it's an object again, then use PROBE FIRST again...
>> probe first system/words
[end! unset! error! datatype! context! native! action! routine! op! function! object!
struct! library! port! any-type! any-word! any-function! number! series! any-string!
any-block! symbol! word! set-word! get-word! lit-word! refinement! none! logic! integer!
decimal! money! time! date! char! pair! event! etc...
I tend to use PROBE FIRST when I just need a quick reminder of the words in an object,
which crops up a lot when working with View faces.
