# SORT ARRAYPTR

Syntax

SORT ARRAYPTR Array pointer SORT ARRAYPTR Array pointer, Field [, Field [, Field [, Field [, Field[, Field]]]]]

Description

These commands are identical to the equivalent SORT ARRAY commands, except that they operate on an array pointer rather than an array. The first form of this command can be used to sort non-UDT arrays into order. If used on a UDT array, an error will be triggered. The second form of this command can be used to sort UDT arrays into order. If used on a non-UDT array, an error will be triggered. Fields are specified numerically - 1 is the first field, etc. If you specify a field that is beyond the end of the format provided, an error will be triggered. It is not an error to specify a field of 0, but the field will be ignored. If the field is specified as a negative number, the field will be sorted in reverse sequence. When sorting strings, null strings and empty are arranged first (and are treated as equal), then by ASCII value of the string contents.
