Hi everyone.
Is it possible to read two file in parallel and grab values from them?
I mean, let's say I have two input file. The first is like this:

alligator-n    attri    aggressive-j    0.0521953848067504
alligator-n    attri    aquatic-j    0.0428300684553727
alligator-n    attri    big-j    0.125268137962678
alligator-n    attri    carnivorous-j    0.0218253043999405
lizard-n    hyper    creature-n    0.618765795370872
lizard-n    hyper    reptile-n    0.466342631493931
lizard-n    hyper    vertebrate-n    0.249202543226053
lizard-n    mero    blood-n    0.397326263768692
dishwasher-n    random-v    prevent-v    0.00856940857204332
dishwasher-n    random-v    qualify-v    0.00675098458337709
dishwasher-n    random-v    top-v    0.0114499058531553
dishwasher-n    random-v    visit-v    0.0134718844088632
freezer-n    attri    big-j    0.0865285153310031
freezer-n    attri    clean-j    0.078801694198009

and the second like this: 
alligator-n    attri    aggressive-j    0.345621780
alligator-n    attri    aquatic-j    0.46634263149393
alligator-n    attri    big-j    0.125268137962678
alligator-n    attri    carnivorous-j    0.0218253043999405
lizard-n    hyper    creature-n    0.618765795370872
lizard-n    hyper    reptile-n    0.466342631493931
lizard-n    hyper    vertebrate-n    0.0428300684553727
lizard-n    mero    blood-n    
dishwasher-n    random-v    prevent-v    0.00856940857204332
dishwasher-n    random-v    qualify-v    0.00675098458337709
dishwasher-n    random-v    top-v    0.125268137962678
dishwasher-n    random-v    visit-v    0.0134718844088632
freezer-n    attri    big-j0.078801694198009
freezer-n    attri    clean-j   0.397326263768692

That is they are exactly the same, except for the last value.
How can I read them in order to confront the last value of each line of the first file with the value of the exactly same line in the second file?For each line I have to apply the following formula: value_from_the first*(1-value_from_the_second).
My output should look like the input, except for the last value, which should be derived as the previous formula suggested.
Thanks a lot.
