using dyalog apl to access )fns function in a script function

Question

I'm trying to use Dyalog APL to generate a function list from within a startup script using: ⍎ ')fns'

but get this error:

⍎VALUE ERROR

Using ⍎ ')fns' in a latent expression script in APLX is not a problem, but I get clobbered doing the same thing in Dyalog.

Help appreciated.

Thanks

Two things:

the )-commands are called "system commands" and their only sensible use is in the APL-Session, not in user-defined functions (because they are just "commands", they do not return a result.)
to get the equivalent of )fnsunder program-control, use ⎕NL 3 or (my preferred way) ⎕NL-3 which returns the result as vector of vectors. The "quad-things" are system-functions that return results.
