File: gdsd_basic.c

Author: J.P. Terlouw

SET, Input CHARACTER*(*)
LEVEL, Input INTEGER
INDEX, Input, Output INTEGER
ERROR ) Output INTEGER

SET Name or handle of set.
LEVEL If specified, the routine only finds items of this
and of higher levels; if not specified, all levels
are found.
INDEX internal index where the search starts.
In the first call of a sequence zero should be
specified. Upon return, it will contain the next
index. If an item cannot be found, zero is returned.

successfully, and an item was found, the level where
the item was found is returned.

By using this routine, one is capable of generating all
descriptor item names. This is useful when transferring data
to a different set or to tape.
