That is because you have used following line to assign the value which is wrong.

x=&x;

In PL/SQL assignment is done using following.

:=

So your code should be like this.

    declare
    x number;
    begin
    x:=&x;
-- Below line will output the number you received as an input
    dbms_output.put_line(x);
    end;
    /

To read the user input and store it in a variable  for later use  you can use SQL Plus command ACCEPT    Accept  lt your variable gt   lt variable type if needed  number char date  gt  prompt  message    example  accept x number prompt  Please enter something      And then you can use the x variable in a PL SQL block as follows    declare    a number  begin   a     amp x  end      Working with a string example   accept x char prompt  Please enter something     declare    a varchar2 10   begin   a      amp x     -- for a substitution variable of char data type  end            -- to be treated as a character string it needs                -- to be enclosed with single quotation marks
