This tool allows you to block columns/row headings so, the first column /or top row will stay on the screen and you also scroll down or over to see the rest of the panel.
mbly code to implement the y=(x1+x2)*(x3+x4) expression on 2-address machine, and then display the value of y on the screen. Assume that the values of the variables are known. Hence, do not worry about their values in your code.
The assembly instructions that are available in this machine are the following:
Load b, a Load the value of a to b
Add b, a Add the value of a to the value of b and pla

Explanation:
Duplicate tuples are not allowed in a relation because the specifications of the constraints of the regional integrity are violated, especially the main constraint that states that there can be no identical values for the attributes of two tuples at any database relation state.
