So you want AMODE 64? But, are you sure you need it?

  • Are you experiencing storage constraints in your applications that you believe would be relieved by having AMODE 64 for your COBOL and PL/I applications?  But, are you really using AMODE 31 effectively?  Might you relieve some of the constraint by better tuning of your use of the LE storage runtime options to control HEAP and STACK usage?  Are you sure your applications are all running in AMODE 31 with the ALL31(ON) run-time option?

    This session will give you some tips and techniques for evaluating your storage usage to try to answer some of the questions above.  And, after doing this analysis, you may also find that you can improve the performance of your applications by more effectively using the storage that you already have in AMODE 31.

    Following this session, you should also attend the "Language Environment Futures Workshop" where IBM will discuss some of the possible ways 64-bit addressing might be exploited in COBOL and PL/I applications.  This subject will be further discussed in a Birds of a Feather session, "Discussion:  The Future of AMODE 64 for COBOL and PL/I," at 6:00PM.

    Tracks: Applications Programming, Architecture, Development Support and z/OS Systems Programming
