The while Statement

Syntax

The while syntax can be expressed as follows:

• for <variable name> while <condition>
  {
               <instructions>   
  }
  

• for <variable name> while <condition>
                  <instruction>
  

• 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
  }
  

Example 1

In the script below, the loop executes until an expression becomes false.

let i = 1 
let x(Point) 

for i while i <=parameter.Size() 
{ 
	x = parameter.GetItem(i) 
	if (x.GetAttributeReal(Y) < 0.04) 
		x.SetAttributeReal(Y,0.04) 
}

• i is a variable name of integer type. It is incremented at the end of each execution of the body.
• X is a variable for points.

Example 2

If the variable is incremented by the user, there is no more automatic increment (automatic increment is an increment of 1 for each loop).

let i = 1
for i while i <=11
{
	  Message(i)
	  i=i+3
}
