The second
BEGIN
WRITE (Num1:S:1,' and',Num2:S:1,' sum to',(NumltNum2)!6:1);
END;
If you specify an expression, PASCAL prints its value. For example,
if Numl equals 71.1 and Num2 equals 29.9, this statement prints:
71.1 and 29.9 sum to 101.0
Note that each of the real numbers is preceded by a space.
Example 3
VAR Rainamts : FILE OF REAL;
Avgrain,Maxrain~Minrain : REAL;
BEGIN
WRITE (Rainamts,Avgrain,Minrain,0.312,Maxrain);
END;
The file Rainamts contains real numbers indicating amounts of
rainfall. The WRITE procedure writes the values of the variables
Avgrain and Minrain into the file, followed by the real constant 0.312
and the value of the variable Maxrain.
