why System command returns right away?

[Ted Zeng]

I run activeperl on Win98 SE, where the script has a line system ( "..."); The command run WinRunner and a WinRunner script. the command lasts for a couple of min., but the perl script continues right away.   It doesn't have this problem on NT4, Win2000.   I also try to Win32:Process:Create to do the same and have the same problem.   How can the script waits until the command is finished before continue?   ted zeng Adobe Systems
