Close file as example: CLOSE (FILE),MODE=31 #1 above GETMAIN location should be BELOW or 24 -- not 31 or ANY. Sorry Ed, but the GETMAIN location is set to ANY. If the DSORG is PO, then I use BELOW for READ and WRITE processing of PDS. But for normal QSAM processing and my example, program is set to ANY. Then I must be confused about what it is you're doing with this GETMAIN. DCBs must (MUST!) be below 16MB in all cases because, among other things, the pointer to the DCB from the DEB is only three bytes long! LOC=ANY implies 31-bit storage (though it *could* actually be satisfied from 24-bit storage if 31-bit storage is exhausted -- very unlikely). We _are_ talking about the *first* (or only) LOC= subparameter, right? The second subparameter controls only the location of the real storage when the page is fixed. Why the unprintable hasn't IBM extended the ACB to handle at least QSAM (and parenthetically allowed concatenation of ESDS and QSAM data sets)? To have to go through the aggravation of getting 24 bit storage in 2006 is one minor symptom for the mainframe not have good long term prospects. Naturally, the above has nothing whatsoever to do with the location of your program.

I think z/OS has very good long term prospects just because of what you think is a symptom. Because of downward compatibility, a program written 30+ years ago can still work today. Things introduced post 31-bit addressing use it. The problem I see for z/OS is what people use it for. Its role has changed from just a batch job machine to a giant server. In terms of capacity to handle a tremendous number of online queries, it can not be beat. Which is why UPS, FedEx and most all large companies rely on the z/Series machines to support their critical workloads. Christopher Y. Blaicher BMC Software, Inc.

Re: (fwd) Re: amode rmode problem
To have to go through the aggravation of getting 24 bit storage in 2006 is one minor symptom for the mainframe not have good long term prospects. You're joking right? We're talking about a minor and pretty insignificant piece of coding to basically maintain downward compatibility with code that is several decades old. It is only of concern for Assembler language programmers who aren't exactly the most abundant element in I/T. So, why should this play into the mainframe's long-term prospects?

Because of downward compatibility, a program written 30+ years ago can still work today. 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.
