`file:load` includes a file and registers the file name into the dictionary.
|
|
With it, the words in the file become viewable.
|
|
|
|
Put file name into dictionary.

Given a word, find the file in which the word was defined.
|
|
Works imperfectly, but useful.

## BUGS
|
|
|
|
The search fails when a word has been defined in a file that was
|
|
not `file:load`ed but `include`d , or
|
|
when the word has been typed in from the console.
|
|
In particular, words in files `include`d before `Load.retro`
|
|
will not be found correctly..
|
|
|
|
Also, words defined in Rx such as
|
|
`push`, `pop`, `drop`, `swap`, and `dup` are not found.
