Enumerating collections of objects

Some objects are defined as collections, that is they can be considered as an array of objects. To extract each one in turn the FOR OBJECT statement, a new variant of FOR, is provided

For example in Microsoft ADO a row is a collection of columns or fields and you can get each one in turn with FOR OBJECT ... IN thus

FOR OBJECT a IN rsTable.Fields()
    PRINT a.Name$, a.Value$
NEXT OBJECT a

FOR OBJECT can be used with any collection object including KCML's built in objects. To enumerate the controls on a form and double their height you can use:

FOR OBJECT c IN Form1
        c.Height = c.Height * 2
NEXT OBJECT c
