pcsoft.us.windevCopyright 2026, PC SOFT20 Jan 2016 11:35:00 Z18 Jan 2016 07:40:00 ZWhat is the current status of rercusive calls in Windev (ie: a procedure calling itself). I found that in the past it was not officially supported. However in the product brochure for WD19 it states that procedures are recursive. Is this actually true now? Are there any limits or problems. Kind of related: what if you have 30 threads running that all call another procedure (say to write a comment to a log file). I assume each call to the procedure would get its own variable space for local variables and that simultaneous use of global variables would need to use semaphores or some other way of dealing with conflicts - does this also fail at some point? Also related: you have 30 threads running and the threadexecute command calls the same procedure: ThreadExecute("Thread1", threadNormal, SensorMonitorThreadProc,"Sensor1") ThreadExecute("Thread2", threadNormal, SensorMonitorThreadProc,"Sensor2") ... Each thread is monitoring a separate external sensor. Is it better in any way to have a separate procedure for each monitoring thread? ThreadExecute("Thread1", threadNormal, SensorMonitorThreadProc1) ThreadExecute("Thread2", threadNormal, SensorMonitorThreadProc2) ... or does it make any difference?30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/55897-wd20-recursion/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)guestpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/55897-wd20-recursion-55951/read.awp20 Jan 2016 11:35:00 ZPeter, I'm using a i5 8Gb 64bit machine, but with 32bit WD versions.
