Things introduced post 31-bit addressing use it. I have no problem with IBM functionally stabilizing the DCB to protect existing programs. I have a major problem with them not coming up with a clean way to access those data set organizations which were not functionally stabilized without having to get 24 bit storage. Indeed we have a major shift coming with 64 bit. IBM COBOL already seems to be steadfastly ignoring it and XPLINK as well. We have the ludicrous situation where instead of implementing the 2002 COBOL standard floating point usages and declaring them to be IEEE floating point leaving COMP-1 and COMP-2 to remain hex floating point, IBM has a glue routine when interfacing with JAVA. I have a major problem with IBM not handling FBA devices despite the fact that all of the strategic access methods (VSAM, PDSE, databases) are FBA. There are still 24 bit modules in TSO and TSO is functionally stabilized despite there still not being a follow-on. > >The problem I see for z/OS is what people use it for.
