Invoking CELQPIPI z/OS Language Environment Programming Guide for 64-bit Virtual Addressing Mode SA38-0689-00 |
|
The interface to the PreInit environment is from a user-written
AMODE 64 PreInit driver. The CELQPIPI service is loaded using the
LOAD macro:
The entry point address returned in register 0 by the LOAD macro will have bit 63 set to 1, which indicates that CELQPIPI is AMODE 64. Bit 63 must be set to 0 before the address can be used by either the CALL macro or a BASR instruction. |
