Together with the NUMRANGE parameter, the RANGLIST parameter allows you to make multiple storage ranges eligible to be assigned to subspaces. The RANGLIST parameter specifies a fullword that contains an address of a list of ranges, or specifies a register that contains the address of the fullword pointer to the range list that you created when you allocated the storage. The number of entries in the range list is specified on the NUMRANGE parameter.

The following examples illustrate the range list and how to use a register or a fullword field as pointers to it.
