Hi Joey,
Hear hear! Long live the command line.
Once browser UI madness has peaked we'll be running IBM3270 sessions in
them again.

Inspired greetings - thanks Hauke and Raul.
My own angle (not code) on it is that I read the emails on my iPhone (a little
tedious) and tried copy/paste of the lines into iOS j - but it didn't work
because of the IDE...
So, logging into my Pi4, using Terminus (a terminal emulator Roger D Mo
Hmm... email often wraps at around 72 characters, and I did not feel
up to the task of squeezing this into a single line not exceeding that
limit. However, maybe a two line approximation might still be
acceptable?

Thank you Jan!
I am 55 now, I still feel as dumb as ever but at least the journey has
been, and continues to be interesting and meeting like minds along the way!
All the best you you in this madness too.

In Sean's case I'd use:
100 3 ?@$ 2 100 100
if a verb is needed for x numbers with specs y I'd use:
stargen=: (, #) ?@$ ]
Don't worry about feeling stupid, I did so for a while too, and it goes
away. Not because you know everything, but because you realise J is really
deep, and there's so many
Oh God, I knew it would happen..
Nice one Hauke!

The value currently is about 400, but that may change without notice.

Henry,
What's the upper bound on that pre-allocated list, that's a good technique
actually. But what do I know?
My main issue was more the fact I couldn't see another way to do it but
both Raul and Clifford have shown me the way.
Seasons greeting to all, I'd express that in J but...

i. 100 returns a section of a pre-allocated list, so it doesn't even
have to generate anything.
(? 100 $ y) is a smidgen slower than (100 ?@$ y)

Generating that list of numbers is trivial, compared to typical
language processing.
Consider a classic "for" loop, which calls a function 100 times. Here,
you are also generating 100 numbers. It's true that they are not
stored in memory simultaneously, but you're also generating 100 stack
frames,
Clifford,
I don't like the boxing either, I also don't like the fact that generation
of a list of numbers that I don't even use (i. 100) just to call a function
N times was the only solution I could find. I almost don't ask questions
around here as it makes me feel even more stupid than I normally
You might look at avoiding the boxing; for example
?10 # ,:3 1024 768
1 259 473
1 628 503
0 672 357
2 1003 559
0 407 117
2 620 116
0 840 45
2 581 444
2 166 629
1 217 202

For the life of me I have failed to just call it and create a table of the
results.
Initially I tried 100 $ stargen 1024;768 but that just calls it once and
cycle repeat
15 matches
