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. The order of the enumeration in not necessarily predictable.

Example :

DIM Dict AS NEW Collection

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

FOR EACH Element IN Dict
  PRINT Element;
NEXT

=> 3 1 2


FOR EACH Expression ... NEXT

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

Example :

DIM Res AS Result

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

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