1. I don't understand the intent of your first sentence here. Are you objecting that the PM solution offered (seems to you) to vary from your instructor's directions? If so, trust choroba's trouble-shooting. Push (see also next graf) allows you to add new elements to an array. When inside a loop, assigning a value to the array REPLACES whatever was in the array on the last iteration of the loop.
2. Perhaps your instructor mentioned using your command line to obtain local help;
   

   C:\> perldoc -f push
   or
   C:\> perldoc -f grep

I'm really confused at this point, my instructor told me to get all the guessing and put them in an array so are you saying I should use push to add onto the @allguess array each time the user enters a number.

There is no put function, see perldoc -f push

$ perl -MData::Dump -e " @a = 1; dd\@a; @a = 2; dd\@a ";
[1]
[2]

$ perl -MData::Dump -e " push @a, 1;  dd\@a; push @a, 2; dd\@a ";
[1]
[1, 2]
