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! 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 == 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. -- Carl Read
