ParameterTypeDescription
subtableSubtableSubtable for which to test if subrecord pointer is
after the last selected subrecord
Function resultBooleanYes (TRUE) or No (FALSE)

Compatibility note: Subtables are no longer supported starting with version 11 of 4D. A compatibility mechanism ensures the functioning of this command in converted databases; however, it is strongly recommended to replace any subtables with standard related tables.

Description

End subselection returns True when the current subrecord pointer is after the end of the current subselection of subtable. End subselection is used to check whether or not NEXT SUBRECORD has moved the pointer after the last subrecord. If the current subselection is empty, End subselection returns True.

Example

The following example is an object method for a button. When the button is clicked, the pointer moves to the next subrecord. If the pointer is after the last subrecord, it moves to the first subrecord:

   NEXT SUBRECORD ([People]Children)   ` Move to the next subrecord 
   If (End subselection ([People]Children))   ` If we have gone too far...
      FIRST SUBRECORD ([People]Children)   ` move to the first subrecord 
   End if
