Interactive I/O

Interactive I/O can be used as alternative to output tab. To view output of your script you need to switch to output tab, otherwise you can use Interactive I/O window to look on script output without switching to output tab. Also Interactive I/O is used to send input to script to STDIN. To send text to STDIN write some text in the bottom edit field and press ENTER. To read this input from your script you may use the following:

$input = <STDIN>;

If you read STDIN in your script, execution of script will be stopped while you don't send anything to STDIN.
