hi,
i am reading a string values from a file.the values are

2000
20000
300
10
5000

now retrieving each value one by one and printing if they are greater than 1000.

i use this statement for the same (in perl script)

if ($_ gt 1000){
print $_
}

but its now prininting all the values.

are the strings form files trated as characters?if so how can convert them to number?any type cast operator?or am i doin anything else wrong?

Are you using perl with the -w switch? That gives a lot of useful information.
I suggest you get the book either "Learning Perl" or "Programming Perl."

Also, If you have a completely different question and have searched and read available documentation and still don't understand, post a new thread.
