ALL31(ON) allows EXTERNAL data to be allocated anywhere within the 31-bit addressing range and improves runtime performance. The IBM-supplied default for ALL31 is ON in the z/OS Language Environment, Version 1 Release 7, or later.
The IBM-supplied default is MSGFILE(SYSOUT).
WSCLEAR and STORAGE(00) do not affect programs compiled with NORENT.
To receive the Language Environment-equivalent of the VS COBOL II WSCLEAR runtime option, set the first suboption of the Language Environment STORAGE runtime option to 00. For example, STORAGE(00,NONE,NONE,8K).
The IBM-supplied default is STORAGE(NONE,NONE,NONE,0K) in z/OS Language Environment.
