if-else: if(expr) statement [else statement] ;
if(score GT 1)

else
result = "negative";
for loop: for (init-expr ; test-expr ; final-expr) statement ;
init-expr and final-expr can be one of the following:
•
A single assignment expression, for example, x=5 or loop=loop+1
•
Any ColdFusion expression, for example, SetVariable("a",a+1)
•
Empty
The test-expr can be one of the following:
•
Any ColdFusion expression, for example, A LT 5, loop LE x, or Y EQ "not found"
AND loop LT end
•
Empty
Here are some examples of for loops:
for(Loop=1;
Loop LT 10;
Loop = Loop + 1)
a[loop]=loop;
// Complete for loop in a single line.
for(loop=1; loop LT 10; loop=loop+1)a[loop]=loop;
// Use braces to indicate multiple statements to loop over
for( ; ; )
{
indx=indx+1;
if(Find("key",strings[indx],1))
break;
}
while loop: while (expr) statement ;
// Use braces to note the code to loop over
a = ArrayNew(1);
loop = 1;
while (loop LT 10)
{
a[loop] = loop + 5;
loop = loop + 1;
}
