I have a text file in which I have some formulas and some conditions like this for many different cases. This text file is auto generated file so there is no standard input.

COND_RULE { L > 0 AND W > 0}
        EM_POLYNOMIAL { 0.3802 + (13.4739 * sqrt(W/0.9)) + (4.6272 * (
+W/0.9))

I want to print out the output of that polynomial through a perl script. I am a newbie to the world of perl. So, I just want to know some ideas and what perl topics should I go through with? Thanks :)
