PREVIOUS SUBRECORD


PREVIOUS SUBRECORD ( subtable )

Parameter	Type	Description
subtable	Subtable	Subtable in which to move to the previous selected subrecord

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

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.

Example

See the example for LAST SUBRECORD.
