I found a reference to fwrite at the following link and it refers me to the
fine Lab "Files" that explains file reading and writing very well. Having
been introduced to J rather early on when print documentation was dominant,
I need to remind myself to search Labs and jwiki for documentation, too.
files script and other essential scripts had been
merged into a single stdlib script which is loaded
automatically by standard profile. For backward
compatibility with j602, load'files' does not raise
any error but it is an no-op. Documentation for stdlib
should be somewhere in jwiki.
you can typ
Well maybe so, but I could not find any mention of fwrite,
and there's no boxing on the right argument.
But that does work.
Thanks.

Yes, that did it. Needed both boxing and jpath,
but I had only tried each separately.
Thanks much.

I think you need to use jpath to resolve ~user
(5!:5 <'t2') 1!:2 <(jpath '~user/filename')

If I understand your comment, I get a different error.
(5!:5 <'t2') 1!:2 <'~user/filename'
|file name error
| (5!:5<'t2')1!:2<'~user/filename'
Also, when I load'files' I can see no result for names/nl:
coclass'base'
load'files'
nl_jfiles_''
nl_files_''
names_jfiles_''
The right argument to 1!:2 should be boxed. You may prefer to use the file
utilities that take care of ensuring the arguments are valid.
