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.
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.
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
