You missunderstood my message: I never use or plan to use global noun by
intention!
It happens to be the case that a noun name remains in a verb definition
that was used in the ijx session by inattention.
In that session the verb runs (with the appropriate test data) but fails
when used in a new session.
As Chris has pointed out, I better start to write in a ijs session
instead of gathering my session hack.
"Discovering" was the wrong word obviously, I should have titled
"finding and removing".

It looks like you are a victim of a particular coding style.
If you avoid using global nouns, it will go away.
Instead, consider OOP and member nouns sparingly, whose number is easy to track.
Refactoring is a good thing.
CASE tools and compilers condone excesses.

Developing J verbs, I mostly proceed as follows:
- get my test data into appropriate nouns.
- try operations and expressions in my session
- copy the right ones into verbs of an ijs-File
- run the ijs-File and try the verbs.
However I often experience the following problem:
- within a verb an extern noun is used
- as the noun is present in the session the error is undiscovered in that
session
- the error occurs when starting a new session
- the definition of that particular noun is not available any more
I'd like to hear how other forum members overcome that problem.
Ideas:
0. Read every verb in painsticking detail before using it.
1. Work with two sessions (with different background colors) a developing and a
test session
2. Write tacit verbs (I often fail to do so)
Question:
3. Is there a verb to find extern referenced names within a verb definition?
looking forward to the discussion,
Markus
