Hi
There is an example of using bypassing post routine in the Authorized Assembler
guide
eliminate the requirement to use the CS instruction. Figure 1 demonstrates an
example of how to quick post an ECB.
Figure 1. Bypassing the POST Routine
L RX,ECB Get contents of ECB.
N RX,=X'3FFFFFFF' Turn off wait and post bits
L RY,=X'40000000' Post bit and post code
CS RX,RY,ECB Compare and swap to post ECB
BZ POSTDONE Branch if CS is successful
LTR RX,RX Wait bit on?
BM DOPOST If yes, then execute POST
N RX,=X'40000000' Is ECB posted?
BNZ POSTDONE If yes, do not execute POST
DOPOST POST ECB
POSTDONE EQU *
I am actually trying to do a XMEM post is this recommend as the other address
space might be swapped out ? thanks
