Scalar found where operator expected -- getting error

gjoshi has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

Hi have three variables I parse the string and find out different values and store it in variables as below: Example

$tmp = "37";
$tmp1 = "<=";
$tmp2 = "4";

#Now I want to use all these variables in if condition.
# I am trying to do following and I am getting an error

if($tmp $tmp1 $tmp2)
{
   # do some thing  
}
else
{
   # do some thing
}

Could you please tell me how to do that. Is it possible?

thanks --girija

Hello gjoshi,

Yes, it’s quite possible. Look at the string form of eval (called eval EXPR in the documentation).

Hope that helps,

You already asked this question here. You should post follow-up questions there if the answer given didn't help you.

The way forward always starts with a minimal test.
