Yes. Because you declare myObject as LOCAL it is visible only in routine where it is declared. So you have two choices:

1. Declare it PRIVATE:
PRIVATE myObject
MyObject = CREATEOBJECT("MyClass")

DO MyProcedure
RETURN


PROCEDURE MyProcedure

   * MyObject is available now
or pass it as parameter:
LOCAL myObject

MyObject = CREATEOBJECT("MyClass")

DO MyProcedure WITH MyObject

RETURN

PROCEDURE MyProcedure(MyObject)

  * MyObject is available
