Hello, A coworker found this and I thought I would share it with you. Its a program that will execute perl and perl won't open a DOS window. Obviously that means Stdout/Stderr will have to go to a file.. but who cares, its free, and it includes source... http://cygutils.netpedia.net/B20/run.html Some caveats.. RunNative.exe must be in same directory as perl.exe, but perl arguments can use full pathnames.. We've tested it an it runs great..
