The .while token behaves like the while keyword in C.

Syntax

.while (Condition) { Commands } 

Syntax Elements

Condition

Specifies a condition. If this evaluates to zero, it is treated as false; otherwise it is true. Enclosing Condition in parentheses is optional. Condition must be an expression, not a debugger command. It will be evaluated by the default expression evaluator (MASM or C++). For details, see Numerical Expression Syntax.

Commands

Specifies one or more commands that will be executed repeatedly as long as the condition is true. This block of commands needs to be enclosed in braces, even if it consists of a single command. Multiple commands should be separated by semicolons, but the final command before the closing brace does not need to be followed by a semicolon.

Comments

The .break and .continue tokens can be used to exit or restart the Commands block.
