To make the assignment statement work, you must declare a type and use it to
declare the variables, as follows:
Alternatively, you could use the declaration:

Unreachable Statements
Pascal flags unreachable statements. Such statements usually correspond to
errors in the program logic, as shown in the following example:
type
r = record
a: integer;
b: char;
end;
var
x: r;
y: r;
x, y : record
a: integer;
b: char;
end;
The Pascal program,
unreached.p
program unreached_example(output);
label
1;
begin
goto 1;
writeln('Unreachable.');
1:
writeln('Reached this.');
end. { unreached_example }
