While Statement

Format

while condition do
// statements
enddo;

Description

The while statement executes one or more statements repeatedly, in a loop, while the logical condition is true. Unlike a do loop, a counter is not automatically incremented, so you must ensure the termination of the loop. The condition is evaluated on each repetition of the loop before any of the statements are executed.

You can exit the loop early by using break and you can continue execution with the next iteration of the loop by using next.

Example

setfile(inputFile, "Countries.txt");

string countriesLine;

while fileread(inputFile, countriesLine) do
// ...
enddo;
