The first range start value must contain 44 bytes of binary zeros. You must arrange the table in ascending order of the 44-byte strings.

The one byte data set number indicates the data set's relative position in the data set name table (ICHRDSNT).

If zero is specified for the data set number it indicates that the range is not associated with a data set. The RACF® manager returns a code of 28 when an attempt is made to access an entity in such a range.

If the data set number is nonzero, RACF assigns the profile for each entry name that falls within the range represented by the 44-byte string to the data set in the RACF database with the corresponding number in the ICHRDSNT table.

When constructing a range table, you must consider the way in which RACF constructs the internal form of the names of certain types of entries. The RACF manager uses only the internal forms of these entry names; therefore, you must also use the internal names when you construct the range table.
