RE: Lack of software abstractions

After I close J and reload the script with your code having put a NB. in 
front of save f  I have:
   f
c:\j601\temp\X.jkf
   load f
|domain error: load
|       load f
   FNAF_floop_
restore my value!

Not quite that simple I suppose...

I disagree.  It is not a serious undertaking, and it is trivial.  It 
took me 6-8 minutes and 3 lines.  Here:

                    require'keyfiles'
                    save    =: (<@:[ keycreate) (3!:1@:(5!:1)@:] keywrite 
,)"0  ;@:((] 
, '_' , [ , '_'"_) L: 0 verb : '<nl__y $~0'"0)@:conl bind ''
                    load     =: < (] 4 : ('(x) =: y 5!:0';'1') :: 0:&> 
(3!:2&.>)@:keyread"1@:,.) keydir


                    f           =:  jpath'~temp\X.jkf'

                    FNAF_floop_ =: 'my original value'
                    save f

                    FNAF_floop_ =: 'restore my value!'
                    load f
                 1 1 1 1 1 ...

                    FNAF_floop_
                 my original value

It has yet to be done because that's not how we do it in J.  That's 
how you do it in APL.  In J, we use script files.

If you want, we can discuss the relative merits of the two approaches.
