hi, thank you for replying, it does not show what I expect it to. it indicates a syntax error near ") print"? Please keep in mind that I am very new to perl and learning bits and pieces :)	[reply]

Make sure you put it inside the loop. The "`{` `}`" brackets contain everything that's inside of your loop.	[reply] [d/l] [select]

Syntax error it says. There's a close bracket before your print it says. Look at the code. Is that the close bracket on your loop list? Did you put the new print inside the curly {}'s of your loop?	[reply]
