HSWORK indicates that
a hiperspace should be used for the WORK library. Specifying NOHSWORK
indicates that the WORK library is not a hiperspace.
NOHSWORK is the default
setting for this option, and this default is probably suitable for
most of your programming needs. However, there might be times when
you want to place the WORK library in a hiperspace. For example, the
performance of programs (with regard to elapsed time) that perform
only output operations to the WORK library can improve significantly
when the WORK library is a hiperspace library. The performance of
programs that perform a mixture of input, output, and update operations
usually does not show a significant improvement in elapsed time.
Note: The effect on performance
of using a hiperspace for WORK data sets is site-dependent. Your system
administrator might want to make recommendations based on investigation
of this issue for your site.
