Table of contents cache entry having a pointer for a range of addresses

A computer program product for facilitating processing within a computing environment, the computer program product comprising:

• at least one computer readable storage medium readable by at least one processing circuit and storing instructions for performing a method comprising:
• obtaining an address of a called routine and a pointer value of a pointer to a reference data structure to be entered into a reference data structure pointer cache, the reference data structure pointer cache comprising a plurality of entries, wherein an entry of the plurality of entries includes a stored pointer value for an address range;
• determining, based on the pointer value, whether an existing entry exists in the reference data structure pointer cache for the pointer value;
• and
• updating, based on determining the existing entry exists, one of an address_from field of the existing entry or an address_to field of the existing entry using the address of the called routine, wherein the stored pointer value of the existing entry is usable to access the reference data structure for the address range defined by the address_from field and the address_to field, the reference data structure to be used to populate variables within program code.
