SAS(R) 9.1.3 Companion for z/OS

458 ISPCAPS System Option Chapter 18
Default: NOHSWORK
Valid in: configuration file, SAS invocation
Category: File Control: SASFILES
PROC OPTIONS GROUP= SASFILES
z/OS specifics: all
Syntax
HSWORK | NOHSWORK
Details
HSWORK indicates that a hiperspace should be used for the WORK data library.
Specifying NOHSWORK indicates that the WORK data 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 may be times when you
want to place the WORK data library in a hiperspace. For example, the performance of
programs (with regard to elapsed time) that perform only output operations to the
WORK data library may improve significantly when the WORK data 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 may want to make recommendations based
on investigation of this issue for your site. R
