Abstract
A linear data set is mapped to one or more non-main storage virtual data spaces. Portions of this data space are then selectively mapped to a 'window' in an address space in which an application is executing, and changes made in this 'window' are temporarily saved in the data space. After completion of processing, the application may permanently save changed data from the data space to the linear data set. The technique for mapping the data space to the address space may be used to map between two address spaces, and may be extended to encompass third and subsequent spaces, so that a reference to a mapped address in the first space will ultimately be interpreted as a reference to an address in the last mapped space.
