Write a program in Pascal if two numbers are positive, then square both numbers

Write a program in Pascal if two numbers are positive, then square both numbers, if both numbers are negative, then find their modulus.

var
a, b: integer;

begin
writeln (‘Enter value a.’);
readln (a);
writeln (‘Enter value b.’);
readln (b);
if (a> 0) and (b> 0) then writeln (a * a);
if (a> 0) and (b> 0) then writeln (b * b);
if (a <0) and (b <0) then writeln (abs (a));
if (a <0) and (b <0) then writeln (abs (b));
end.
