Need Help??

print can take a list as an argument, thus the return value (1 ie. true) of the print"no" gets printed (comma is a list separator).
exit gets evaluated and your script exits.
The last part of your statement is evaluated first, that means that if( $var ) exit is executed first and it exits.

Update: corrected #2, thanks ikegami

seek $her, $from, $everywhere if exists $true{love};

`exit` evaluates given expression, your `print` statement in this case and exits. No. `exit` is evaluated with no arguments in all of the OP's snippets. `print"yes",exit ,print"no" if ($var)` [download] is the same as `print( "yes", exit(), print("no") ) if ($var)` [download] That's because `print( "yes", exit( , print("no") ) ) if ($var)` [download] is illegal.

Ah, I stand corrected, I missed the comma :-) -- `seek $her, $from, $everywhere if exists $true{love};`	[reply] [d/l]
