Some functions that are used in the 'layout function do apparently not exist, yet 'layout works fine. But when you try to replace the 'layout function by an adapted version containing some debugging statements, the functions and undeclared variables will immediately cause an error.
The functions BIND? and BOUND? don't show results for, for example, the used TRACK function, so there is no extra information by using those. Special interest in the do-facets and grow-facets functions.

You can find the definitions in the source files of the sdk e.g
track: func [blk] [if verbose [print blk]]
in view-vid.r
Here a helper function to get the definition/source of a word/function in an unknown context and e.g. without access to the sdk
find-anon: func [ words fn /local ] [
foreach word words [
if word = fn [set :fn probe get word halt]
if block? word [
find-anon word fn
]
]
]
find-anon second :layout 'grow-facets
help grow-facets
Here are two ways to create anonymous contexts in Rebol 2:
In the first form you may reach the context of the word
semi-hidden-function:But in second form you may not:
I see many Rebolers use one of above forms, not only to hide but to keep the main function clean and separate.
Here I also add the functions you like to see, it is a bit long so I compressed & enbased:
You can simply paste below line to the console, copy the below text and execute the line to decompress it:
