Hi Bill,
It works fine with the dependencies installed!
However, there are some security issues because the two components needed (dll
+ exe) have been retired by Microsoft and can now only be obtained from generic
software download sites.
The linux side failure was just an issue with a

Hello,
The name of the dll for the Java virtual machine on Windows needs needs to be
corrected in jni.ijs (line 308):
libjvm=. '"', '"',~ jvm, (('Darwin'-:UNAME) +
IFUNIX){::'libjvm.dll';'libjvm.so';'libjvm.dylib'
should be changed to:
libjvm=. '"', '"',~ jvm, (('Darwin'-:UNAME) +

_. also does weird things as the x value for ".
NB. the following work as expected:
_". '25'
25
_". 'Haoussa'

_". 'Gisir'

_.".'Haoussa'
_.
_.". 'GISIR'
_.
NB. but somehow this fails on some magic values:
_.".'Gisir'
|NaN error
| _. ".'Gisir'

Hello,
_. does not mix well with logical operators. The following hang and use a lot
of CPU on J 9.03 (Windows and Linux):
1 +. _.
1 *. _.
+. / 8 0 _.
Note, that I have no particular use for these sentences, I just stumbled across
them due to a bug in my program.

Thank you all for the tips!

Actually it wasn't ok. It turned out that Jqt >> about showed that is was
running J9.02 when installed from /usr/bin - and not 9.03 as when run in from

I then tried to solve conflicts by removing all my old J versions installed in

Thanks Raul. Very helpful indeed.

In similar situations -but my files are not huge- I extract what I want into
flattened CSV using one or more XQuery scripts, and then load the CSV files
with J. The code is clean, compact and easy to maintain. For recurrent XQuery
patterns, m4 occasionally comes to the rescue. Expect minor port
I agree Robert, symbols are a logical fit if hash tables are implemented.
Symbols are a regular part of my diet (small size and quick checking of
equality). The closest need to hash tables I have come across is looking up
data in a table where one column is a symbol. Usually I look-up many ite

Justin,
On a very pragmatic level, I just use CSV as the interchange format. Not ideal
but it works.

ssconvert ships with gnumeric, works pretty well and is low hassle

The difficult part in my experience is describing the structure and
