Sorry, but the way you asked your question is really not that clearly worded.

Have you tried the rsh command from your Windows command line to see if you can get in an run the perl script?

If you do that, you will see that the script is waiting for input. The system command does not seem to supply that input, so the window appears to freeze because there is no input being supplied.

Sorry, I means I use perl script on Windows, then remote call perl script on Unix which will ask me to input data.
I have tried it's ok of remoting call.
So, I don't know why I enter "enter" so fast, the screen console will be freezed, but when I input data, then enter "enter" slowly, there is no problem.
Could you try my script?
Thank you.

Regardless of "where" you are executing the script from, it is still being done remotely. The script you seem to be executing is expecting input. Is the rest of your script supplying that input or is this all of it ( just a system function with an rsh command)? If this is all of it, then (as I said), the window appears to be freezing because it needs input.

Running two input forms on the same page, one php and the other (the one I would like to create) to be written in perl. The idea is to accept an input from a perl script, then pass that input to two other input fields, one in perl and the other in php. The two existing input fields (perl and php) are stand alone scripts. The perl script searches a flat text data base, while the php script searches a MySQL data base. The end result desired is to...
