The utility subroutines are described in this chapter.
The utility subroutines perform general service functions that support
ESSL, rather than mathematical computations (Table 166).

£ This subroutine is provided for migration from earlier
releases of ESSL and is not intended for use in new programs. Documentation
for this subroutines is no longer provided.
