Function DbSetDescend() Foundation
Reverses the navigational order of a work area.
DbSetDescend( <lDescend> ) --> NIL
The return value of DbSetDescend() is always NIL.
The function DbSetDescend() is used to quickly change the navigational order in a work area from ascending to descending and vice versa without the need to create a corresponding index. When .T. (true) is passed to the function, the navigational order is reversed, i.e. all functions and commands that move the record pointer are inverted.
|DbGoTop()||Positions the record pointer on the last record|
|DbGoBottom()||Positions the record pointer on the first record|
|DbSkip( 1 )||Moves the record pointer to the previous record|
|DbSkip(-1 )||Moves the record pointer to the next record|
|Bof()||Returns .T. when attempting to move the record pointer behind the last record|
|Eof()||Returns .T. when attempting to move the record pointer before the first record|
