Dinum

DINUM

(Optional) Identifies the subscript at which the data is to be stored, that is, the internal entry number of the new record, shown as follows. (This means that DINUM must be a canonic number and that no data exists in the global at that subscript location.)

$D(@(DIC_DINUM_")"))=0

If a record already exists at the DINUM internal entry number, no new entry is made. The variable Y is returned equal -1.
