Attributes

res=

Associates a location in a window with a request for specific information. The value is an integer from 1 to 64 000.

Description

:ddf. indicates that the application will provide dynamically formatted data.

When IPF encounters :ddf., it sends the message HM_QUERY_DDF_DATA to the OBJCOM window, and specifies the res= value. (The application identified the OBJCOM window by sending HM_SET_OBJCOM_WINDOW to IPF.) The OBJCOM code responds by initializing for dynamic data formatting and proceeding with a dynamic data-formatting routine, using dynamic data-formatting functions. For more information, see Changing Help Information at Run Time (DDF).
