[REBOL] Re: Command/Pro call interact with external program using STDIO

From: micael:gullmes:telenor:se at: 30-Jan-2003 9:31

Hi Gabriele, if it works, that would be a neat solution! Unfortenatly I do not have the time to dig into it rigth now, I have a tight deadline for the project I am working with. I will work around it in a quick'n'dirty & more CPU/memory consuming way. I.e. calling the external program multiple times, not a nice solution, but time is my enemy here. I hope I get some sparetime to start looking into this ata later stage, but since my knowledge about ports are limited, it will probably take lots of time.

CALL allows you to pass a port for the /INPUT and /OUTPUT refinements. You could write your own port handler to have the functionality you desire. I cannot guarantee that it will work because I know there are some problems if the way CALL handles IO redirection, but in theory it should work. :-) Regards, Gabriele. -- Gabriele Santilli <[g--santilli--tiscalinet--it]> -- REBOL Programmer Amigan -- AGI L'Aquila -- REB: http://web.tiscali.it/rebol/index.r
