The for Statement

Syntax

The general form of the syntax can be expressed as follows:

For <variable name> inside <list variable name>
{

}

For <variable name> while <condition>
                <instruction>

Use

You can use the for statement to execute a loop based on the element of a list. The form of the syntax can be expressed as follows:

let List1(List) 
       let x(Point) 
       For x inside List1
       {
               ... Body ... 
               if (x <> NULL)
                    ...
       }

Where:

x is a variable name (of a given type). It can represent an object or a value.
x can be used in the body (like any other variable of the language). It contains the element of the list corresponding to the current iteration.
List1 is a variable name of type List or an expression returning a list.

Notes:

The body is executed Nth times where N is the number of elements of the list.
You can declare the variable at the beginning of the script. The variable of the loop must be an integer:
```
let i(Integer)
for i = 2 while i<50
{
//EKL Actions
}
```
You can initialize the variable with an instruction that returns an Integer. The variable of the loop must be an integer:
```
let i(Integer)
for i = 2*2+1 while i<50
{
//EKL Actions
}
```

You can use the for statement to execute a loop that stops only when an expression becomes false. The form of the syntax can be expressed as follows:

For x while predicate 
       { 
         ... Body ... 
       }

Where:

x is a variable name of integer type. It is incremented at the end of each execution of the body unless it has been explicitly changed in the body.
predicate is a Boolean expression. The body is executed if this expression is true. This expression is evaluated before the body.

Note: Using the for statement in such a configuration can lead to infinite loops.
