[Jprogramming] timer in j701?

How do I get a timer in j701 jhs (or jconsole)? I've been assuming wd (11!:0) doesn't work at all in j701 (in j602 you'd do: 11!:0 'timer 3' for a callback in 3 secs). BTW J701 help (http://www.jsoftware.com/docs/help701/dictionary/dx011.htm) still refers to 11!:0 but I assume that's just because

There is no JHS equivalent of wd'timer'. I think this would best be done in JHS with a javascript asynch timer that does an ajax call. If you get stumped on this, get back to me. On Thu, Jan 5, 2012 at 11:23 AM, Ian Clark wrote: > You're right, Bill, there's no timer in j602 jconsole either. But

Thanks Eric. I'll take a stab at it. It will be instructive. But I may well be getting back. To make my requirement more precise, I want to trigger some "handler" verb after a given interval, leaving J to carry on working normally, but to do it only once, not repeatedly. That's the only use I make

You are welcome, Ian. I am a bit curious about J support for dylibs. I currently do not have any way to try it myself, but the J DLL documentation does say: J can call procedures that are compiled in a shared library file. In Windows these files are called DLLs (dynamic link libraries) and hav

Re: [Jprogramming] timer in j701?

cd (calls to external libraries) works on all platforms and specifically J can use cd to call dylibs on Mac. However, the timer routine you referred to is windows only and I don't know of the mac equivalent. A dylib call is probably not the way to provide timer events for JHS regardless of server p
