Introduced: Version 1.3.b46

Repeatedly executes a statement until a condition becomes false.

[WHILE(condition): body]
[WHILE(condition, separator): body]

[h:num = 10]
[WHILE(num >= 0): num = num - 1]

Outputs 9,8,7,6,5,4,3,2,1

This example demonstrates how to put multiple instructions inside a while loop using the CODE block extension.

[h: End = 5]
[H: Num = 0]
[WHILE(Num < End, "<br>"), CODE: {
    Number is [Num = Num + 1],
    Next will be [Num+1]
}]

Outputs Number is 1, Next will be 2 Number is 2, Next will be 3 Number is 3, Next will be 4 Number is 4, Next will be 5 Number is 5, Next will be 6
