Details

HSWORK indicates that a hiperspace should be used for the WORK library. Specifying NOHSWORK indicates that the WORK library will not be 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. [cautionend]
