Ah, the `exec` is NOT failing. It's the Perl script that's failing. It doesn't like the arguments you passed to it. You probably used `exec("program $arg1 $arg2")` without quoting and escaping the contents of arg1 and arg2. (Injection attack vulnerability!) You could properly quote and escape their contents properly, or use `exec("program", $arg1, $arg2)` which calls the program directly instead of passing the command string to an intermidary shell.

Well, I'd buy that arguement if the code had any arguements. I've narrowed it down by running this: `#!c:\Perl\bin\Perl print "\n Line from print_1.pl \n"; exec "print_2.pl"; print "\n ERROR from print_1.pl: $! \n"; __END__` [download] And I get this result: `j:> print_1.pl j:> Line from print_1.pl j:> ERROR from print_1.pl: Invalid arguement` [download] I probably didn't explain well enough that ther same code works just fine on another Windows server. Obviously a setting somewhere that different. But that's where I'm stumped.	[reply] [d/l] [select]

On a Windows machine? Try `exec 'perl', 'print_2.pl';`. Use the full path to `perl` if necessary.	[reply] [d/l] [select]
