glad you enjoyed,
the conjunctions also let you cut down on parens
to banish even more of them:
bea=: 1 : ';/ m'
ba=: 1 : '< m'
wa=: 1 : ';: m'
'total quantity'ba 4 2 ba} (([: +/&.:> 1 1 to 3 1 { ]) 4 1 ba} ]) 'rice beans
eggs'wa 1 0 to 3 0 } 1 2 3 bea 1 1 to 3 1} 'foods qty'wa 0 0
Pascal, thanks for sharing. It reminds me of sc in some ways. I doubt I'd
use it for this purpose but it was fun to play with and it seems like an
easier syntax for ammend
]s=:5 3 $ <''
]s=:(<'foods')(0 0 to 0 0) } s
]s=:(<'qty')(0 1 to 0 1) } s
]s=:(<"0@+&1@i.3) (1 1 to 3 1) } s
]s=:('rice';'bean
sorry, mistyped to2
to2
=: [: <"1 [: ,."0/&>/ [ +&.> [: i.@:>:&.> -~

spreadsheets have a range selection syntax like A1:C3&F4~B2 which means the
block range from A1 to C3 with the cell F4 added, and the cell B2 removed.
Ignoring the letter conversions, here are some useful J functions for building
a list of selectors (can be used with both { and }). Conjunction
Sorry. You are correct.
The following comment appears in j engine source. I guess this
was written more than a decade ago when 64-bit COM was uncommon.
But by now, there is not so much incentive to support 64-bit COM.
//! 64 bit problems - com and dll interface is 32 bit - needs test and thought
The subject said JDLLServer which should be available in all
versions of J engines. You need to run the batch file included
to register the COM server. If you use the AIO installer, this
will be done for you.

I curious as to what version of j64 you are using. Are the COM servers
still embedded in j8.02?
Yes, they are. :)

Thanks for your reply.

Yes, that right. Integers like int or Int32 have a size of 32 bit, but
that is not the problem here. Already the _j.GetB always returns box

I'm not an expert on C#, but it seems that int is always 4-byte whether on
32 or 64 bit, so that you propably need int64[] for J64.

I have an issue with the 64-bit JDLLServer in relation to 64 integers.
It seems that JDLLServer handles only the lower 32 bits of a 64 bit
value. The following test demonstrates this issue:
Test (C#):
var value = 1000 + ((Int64)1 << 32);
_j.Do(String.Format("a =: {0}", value));
Assert.AreEqual(
