Using a Macro to copy to first blank cell that is variable - excel

Question

I am trying to modify the below code so that it will be able to copy from one workbook to another and paste in the first empty blank cell in column A. For example if I copy and paste from A1 to E18 from one workbook, I want to be able to modify the code so that it opens a second workbook and copies and pastes the code from A19 (the first blank cell in A). I am greener than green when it comes to VBA programming. I have looked at examples for similar situations but have not been able to figure out how to apply them to what I want to do. Thank you!
