The READ and READLN instructions read a variable from the keyboard. The comand will continue to read until ENTER is pressed (with an exception). In contrast with READ, READLN reads the variable and, when the user pressed ENTER, it moves the cursor on the next line. These instructions can read one variable or more variables. For example: read (x); {reads the variable x} read (a,b,c); {reads a, then reads b, then reads c}
