@ -1414,37 +1414,29 @@ The second variation of the if-statement is to allow for the use of
Else and If-Else cascading statements. Examples of such statements are Else and If-Else cascading statements. Examples of such statements are
as follows: as follows:
Example 1: Example 2: Example 1: Example 2: Example 3:
if (x < y) if (x < y) if (x < y) if (x < y) if (x > y + 1)
z := x + 3; { z := x + 3; { y := abs(x - z);
else y := z + x; else y := z + x; else
y := x - z; z := x + 3; y := x - z; z := x + 3; {
} } y := z + x;
else else z := x + 3;
y := x - z; y := x - z; };

if (x > y + 1) if (2 * x < max(y,3))
y := abs(x - z); {
else y := z + x;
{ z := x + 3;
y := z + x; }
