Until

Description

Loop based on an expression.

Until ( <expression> )
{
    statements
    ...
}

Parameters

expression

If the expression is false the following statements are executed. This loop continues until the expression is true.

Same as a WHILE you can omit the expression however this loop will never execute if you do that.

Remarks

Until statements may be nested.

The expression is tested before the loop is executed so the loop will be executed zero or more times.

To create an infinite loop, you can use a zero number as the expression such as "Until ( False )"

The expression can contain the boolean operators of &&, ||, ! as well as the logical operators <, <=, >, >=, ==, !=, <>, eq, eqi, neq and neqi as needed grouped with parentheses as needed.

Example

$i = 0;
Until ( $i > 20 )
{
	println( "Value is: " . $i );
	$i++;
}

A reverse Until

my $i = 0;
println("Value $i {\$i++!}") until($i == 10);
