PREVIOUS SUBRECORD
PREVIOUS SUBRECORD
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. PREVIOUS SUBRECORD moves the current subrecord pointer to the previous subrecord in the current subselection of subtable. If PREVIOUS SUBRECORD moves the pointer before the first subrecord, Before subselection returns TRUE, and there is no current subrecord. If Before subselection returns TRUE, use FIRST SUBRECORD or LAST SUBRECORD to move the pointer back into the current subselection. If the current subselection is empty, or End subselection returns TRUE, PREVIOUS SUBRECORD has no effect. See the example for LAST SUBRECORD. |
