Red Rum, I saw this post and was curious. Rather than cheat, I thought I would take a guess as to what happens in this and then test my guess later. If I didn't do this, then no one will see the point of your exercise. So, here goes: print (1 + 2) + 4; In this, the (1 + 2) portion of this is the real arguments to the print function. Therefore I believe that '3' should be printed to STDOUT. Since you did not assign a variable to the return result, $_ should have the value of the returned value from print(), which if it printed is '1', plus '4', the sum of which is 5. So, if you print $_ next, it would be '5'. Next, looking at your second example: print (1 + 2) + (4 + 4 + (3 + 3)); I believe that '3' should be printed to STDOUT again and a print of $_ would print 15, the sum of the return value '1' + 14. Now, I will go test this. Good example of how not to program. Dennis $a="c323745335d3221214b364d545". "a362532582521254c3640504c3729".
