For

for( initializer; condition; increment ) loop

•	initializer	–	Executed once just before checking condition.
•	condition	–	If this executes as true then loop is executed.
•	increment	–	Executed after loop, then condition is checked again.
•	loop	–	Can be either a single statement, a block statement, or a null statement.

Any of the statements can be null statements.

**Conditional Types**
Type	Condition
integer	True if it is not zero.
float	True if it is not zero.
string	True if its length is not zero.
key	True only if it is a valid key and not NULL_KEY.
vector	True if the vector is not ZERO_VECTOR.
rotation	True if the rotation is not ZERO_ROTATION.
list	True if the length is not zero.

//single statement type.
integer a;
integer b = 10;
for(a = 1; a <= b; ++a)
    llOwnerSay((string)a);

//block statement
integer a = 0;
integer b = 10;
for(; a < b; ++a)
{
    llOwnerSay((string)a);
    llOwnerSay((string)a);
}

//null statement
integer a = 0;
integer b = 10;
for(; a < b; llOwnerSay((string)(a++)));

A for loop is the same as a while loop as below.

initializer;
while(condition)
{
    loop;
    increment;
}
