Example 1:: while { a < b } do { a = a + 1 };
Example 2:: A practical example: Repair all members of a group to such a level that they are able to stand up: { while { (not canStand _x) and (alive _x) } do { _x setDammage (getDammage _x) - 0.01; }; } forEach units group unitname;

Kronzky: The boolean code that's used to evaluate the while condition can be preceded by code that executes a regular command.
e.g. while {_a=_a+1; _a<10} do {...}; Posted on January 2, 2012
Lucky44: Different than in IF statements, the condition in a WHILE loop can use curly braces not parentheses, unless it has multiple conditions, as shown above. So this will be a problem: while (variable1 == "wait") do... But this will work: while {variable1 == "wait"} do...
