Loops

Loops allow a chunk of code to be executed as long as a control condition is valid (true) or for specific number of iterations. In Delphi, you manage loops either by using a while, a repeat, or a for statement.

While Statement

A while..do statement executes the designated code as long as the condition that appears between the keywords while and do (control condition) is true. The evaluation of the control statement is done in the very beginning of the loop, which means that the relevant code may or may not be executed at all.

var

  whileControl: Integer;

begin

  whileControl:=0; ...
