I would not rule out > 8 character mnemonics nor > 8 character HLASM assembler directives (not that I'm currently planning any). Because of the very large number of mnemonics and extended mnemonics which have been added, there are some ISPF SuperC commands to assist users in searching their source, copybook and macro libraries to see if they may be affected (http://www.ibm.com/support/docview.wss?uid=swg21694301). The new instructions have highlighted a problem for which we have to strike a balance. Several of the new instructions have the same mnemonics but differing instruction formats. Who can successfully execute ESA/390 vector instructions ? But some users will have these mnemonics are coded in their applications (anyone want to own up having some?). Should we always (100%) maintain the ability for users programs to assemble programs cleanly even though they would not execute successfully? How much can a product change (or evolve) without users having to make some or consider those changes ? IBM z Systems have a very long history of minimising the affect of changes on users - but products and their usage change over time. How customers use our products changes over time. Is that progress ?
