As Dan says, the usual way J handles a group of variables is with an array.
I'm still interested in seeing a realistic example of how OOP provides
something useful for organizing code
The toy examples usually trotted out - different geometric shapes or cars
- do not seem convincing.
a performance is much better.

Since I know J, I deduced from the list of allowable left arguments to
"jpkg" that this
(<'install') jpkg&.>0{"1 'shownotinstalled' jpkg''
works but it seems far from intuitive or simple.

Hi -
I was just burned by this apparent anomaly:
1 e. 0~: i. 2 2
0
but
1 e. , 0~: i. 2 2
1
Has anyone else noticed this? Am I right in thinking this is incorrect
behavior in the first case?
Regards,
Devon
