There are a pair of verbs in J602 JWD: runimmx0_jijs_ and runimmx1_jijs_ . What do they do?
(You may assume I've read about 9!:26 et seq in ~help/dictionary/dx009.htm -but don't grok the word "immediate".) I've been finding runimmx1_jijs_ useful for executing a given statement from within J code as if it had been typed into the J session. Occasionally doing this behaves differently from running it as a bare line of code in a verb. For example: cocurrent 'mylocale' --which stops the current locale reverting on exit from the calling verb and forces it to remain in mylocale. Something one wouldn't normally need to do in operational code I guess. But it's convenient for writing what used to be called CASE tools. (The need arises in-part because I can never spell "cocurrent" right first time :-) Are there implications? Am I misusing the facility? What should I really be doing? An allied matter (at least I think so)... APL+Win has a facility called "Defer" which posts a statement to be executed only when the current process has finished running, typically a gui control handler and its nested calls. Good for gui housekeeping. I've been approximating this effect by setting systimer to execute (once only) the required statement as a callback, a millisecond or so in the future. It's a cumbersome way of doing things. Is there a neater way? BTW I'm using a Mac under Snow Leopard. Things which work under Windows can't be guaranteed to do so on the Mac, and vice-versa, because the system event queues are a bit different. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
