Is there any difference in performance if we have AMODE 31 and AMODE 24. i thought of asking this because the system has to use address of 31 bits.

Will there be any performance difference if we have AMODE/RMODE as 24/24 and AMODE/RMODE as 31/ANY?

thanks,

Hello,

None that i know of.

AMODE and RMODE shouldn't change the internal speed of the instructions or the i/o.

I think Dick is right but I should add something that may be obvious...

Always use 31 unless there is a reason not to. If all your programs were linked using 24, then a growing application would eventually run into storage issues.
