Loop Icon Properties

→ File:Loop Flowchart Icon.png → File:Loop Properties.png

Loop icons are used to repeat a task until specified conditions are fulfilled, or to perform the loop a set number of times. Note that you will need to add calculation icons that modify the variables used for the condition in order for the condition to be fulfilled.

Display Name

The name of the icon that appears on the flowchart.

Loop while

Loops the program until the specified condition becomes true. Enter the conditions which will fulfil the loop. (Setting the test condition to something that is always true will make the loop repeat forever e.g. While 1)

Variables Arrow

Clicking on the down arrow brings up the variables dialog window allowing you to select an existing variable or to create a new one.

Test the loop at the:

Select whether you wish the loop to be tested at the start or at the end of the loop. Can be set to check the condition at the start of the loop or at the end of the loop.

Loop count

Sets the loop to loop through a set number of times. Count must be a whole number between 1 and 255.

Infinite loops

Sometimes a task needs to be repeated continually. One useful way of achieving this is to have an infinite loop. Setting the test condition to something that is always true will make the loop repeat forever e.g. While 1
