SET DESCENDING
Change the descending flag of the controlling order
------------------------------------------------------------------------------
Syntax
SET DESCENDING ON | OFF | (<lToggle>)
Arguments
ON enables the descending flag.
OFF disables the descending flag.
<lToggle> is a logical expression that must be enclosed in
parentheses. A value of true (.T.) is the same as ON, and a value of
false (.F.) is the same as OFF.
Note: The initial default of this setting depends on whether the
controlling order was created with DESCENDING as an attribute.
Description

this function for more information.

can be both ascending and descending:
