FOR EACH
FOR EACH Variable IN Expression
  ...
NEXT

Repeats a loop while enumerating an object.

Expression must be a reference to an enumerable object: for example, a collection, or an array.

Example

DIM Dict AS NEW Collection
DIM Element AS String

Dict["Blue"] = 3
Dict["Red"] = 1
Dict["Green"] = 2

FOR EACH Element IN Dict
  PRINT Element;
NEXT

3 1 2

FOR EACH
FOR EACH Expression
  ...
NEXT

This syntax must be used when Expression is a enumerable object that is not a real container: for example, the result of a database query.

DIM Res AS Result

Res = DB.Exec("SELECT * FROM MyTable")

FOR EACH Res
  PRINT Res!Code; " "; Res!Name
NEXT

The order of the enumeration in not necessarily predictable. See the documentation of each enumerable class for more details on that.
