IGZETUN

IGZETUN is a COBOL tuning module provided during installation that contains default values. These values affect the way space is managed at run time.

Hints

Take care if you change the values provided by IBM in this module. Set block sizes and rounding factors with the page size of your system in mind. Realize that any part of your blocks not used by COBOL will be unused in virtual storage and thus wasted.
