Hi all, I'm not sure wether this is the right group for my question, but as Dyalog APL is involved I hope it might be... I have a strange problem with the...

Dear Mr Chaudhary You make an excellent point. Arthur Whitney, author of the A+, K and Q languages, tackled this point in his address at the Royal Society in...
What's wrong with the picture below? Or, is it right? Thanks to anyone for explaining the two items able to evade the penetrating gaze of the DISPLAY...
I think Phil is right. DISPLAY uses []FMT, which formats the backspace character as a 0-column matrix. Perhaps DISPLAY should show a squish or blank for...
I'm a little confused. Is the zero'th item character data? That is, []io 0 []av <iota > qq[0] DOMAIN ERROR []AV <iota> qq[0] ^ Some of you may recognize qq as...
I tried it again and I'm getting more satisfying results. Is it possible DISPLAY yields different results depending on when it looks at qq[0]? Originally, no...
I have fixed the easy part of this problem: The display function was not coping well with scalar terminal control characters. See new version of display in...
Using the Microsoft Web Browser control, you can easily display MS Word documents (and much else) under a Dyalog APL window. When viewing a word doc, you can...

Say I have a multi-threaded app, and I have a dfn that I want to execute in its entirety without thread switching. I can't use :Hold, because the dfn is...
I also believe it to be true; easy enough to test; but beware, do not call any other dfns, even in-line anonymous ones within your code because they also are...
Thread switching occurs only on entry to a dfn, not at line change, so diamonds are not necessary. Thread switching can occur when: - An inner dfn is called. -...
... so diamonds are not necessary. Wow, that's perfect! I was just formulating a question along the lines of "I'd like to able to specify certain functions to ...

How does one deal with the nagging feeling that their APL algorithm is not as efficient as it could be? What I mean by this is the following: Suppose you were...
One could subscribe to Vector (www.vector.org.uk) and practice by trying to write functions that perform faster than the some of those in the "limbering up"...

Have to agree with Ray here. Sounds like a case of premature optimization. Less important than whether or not APL is doing any "extra" calculations is whether...
I have believed for decades that it was a shame that dyadic iota was a function rather than an operator which took a boolean function on its left . Thus your...
why do i see apl chars in phil last's posts to dyaloguers when viewing in yahoo webmail via firefox. . . but i can't see apl chars on vector.org or dyalog.com?...

Actually I cut and pasted out of the dyalog session and Firefox dropped it in as an image I could have right clicked and chosen "Paste without formatting" but...
