1. Spawning a process without waiting for a return

Hello, is it possible to use the Euphoria task handling to spawn other processes, without the main Euphoria program waiting for those processes? The spawned processes should have seperate process id's as if they were seperate programs. In fact the spawned processes may still be executing while the main Euphoria program is complete. I need to do this in the Windows 7 and XP environments, to test some wacky customer batch sheduling system that does this ;)
Both system() and system_exec() wait for the invoked process to finish. Even specifying system("call program_name") waits. I found a solution in the archive that uses dos interrupts, but thats obsolete :(
Any suggestions, even if it is not done through Euphoria tasks? TIA

Win32Lib wraps shellExecute and shellExecuteEx. Pete Lomax had wrapped that as well (or updated some code from Juergen Luethje), but the link in the archive is broken. I'd guess that Arwen wraps it as well. wxEuphoria has its own wrapper, too.

Thanks Matt! I will see what I can find in those, beginning with Win32lib.

Matt, you are a star! The shellExecuteEx did the job, working as designed :)

In case anyone wants that code, it is available as part of Edita and/or Phix (syswait.ew)

FWIW, I tried to upload my code of about 2 pages delimited by the Creole euphoria formatting options, but it can't get past the preview. Anybody interested in my code, let me know and I will send it.
Thanks!

a better way for code of more than a page is pasty on openeuphoria
the preview must be broken if it silently fails. maybe it's an anti spam measure.
