From a GCC perspective, one would normally expect to produce programs that operate with GNU's library. True. What might be nice, on z/OS, is to implement a library of stubs which are glibc compatible, but map the glibc calling sequence into the associated LE subroutine's calling sequence. Well, at least __I__ think it would be nice. Using GCC on z/OS is a collision of technologies that were not designed to work together. GCC is designed with glibc in mind, and IBM XL C/C++ is designed with the LE runtime in mind. If GCC and the LE runtime are to inter-operate, then something has to give. If I was someone porting an app developed in GCC on another platform, then I might be hoping that it would use glibc and run just like it did on the other platform. On the other hand, if I (like you) was someone wanting to do do new C development on z/OS, then I might prefer it if the compiler output could talk to the LE runtime. Needless to say, IBM would prefer to see the first option above rather than the second! I actually rather like the CEEDUMP output. It is well known that I am weird. To each his own on that one...I try to ensure that I always get a real dump instead of a CEEDUMP, and I eliminate LE's ESPIE whenever possible as well. -- Regards, Gord Tomlin Action Software International (a division of Mazda Computer Corporation) Tel: (905) 470-7113, Fax: (905) 470-6507 -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: Calling idcams
IGGCSI00 is only for doing the equivalent of a LISTCAT type function. You could call IDCAMS itself, with I/O exits to feed it the required commands as if they had come from SYSIN. Or you might want to set up a TSO environment and invoke the TSO commands. If you want to do the former (call IDCAMS using I/O exits), you can download file 864 from http://cbttape.org/updates.htm . It is some UNIX commands, one of which is called ams which uses IDCAMS with I/O exits to implement a z/OS UNIX command which prompts the shell user for IDCAMS commands and returns the result. The package is in standard CBT format (zip of an XMIT of a PDS). But the source is in a member in the PDS which is the output from a pax command. Which means that the reload job, included in the package, restores to a z/OS UNIX subdirectory. You can then use ISPF option 1 or 2 to list this subdirectory and then edit/view/browse the source code (in file ams.s) for an example. Another possibility (not sure) is to set up a TSO environment in your code using IKJTSOEV and then invoking a REXX program to issue the TSO commands. I don't know if this will work. And, IMO, it is inelegant. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.

Re: Calling idcams
John, I am a big fan of elegant. I know how to perform the IDCAMS functions via rexx, no problem. I am toying with a called C solution, which is our stated direction. I like the Unix solution I will take a look at File864 on cbttapes.org. There is a lot of good code by good people on those cbttapes and xephon pubs.

Why I/O exits? What's wrong with POSIX pipes? Easier for me to write I/O exits than to set up and allocate the pipes to SYSIN and SYSPRINT. Yes, I guess that I could have used pipes. But it is simplier FOR ME to use I/O exits. Especially in HLASM. Remember that I don't have a C compiler. What are the APF constraints on IDCAMS? I understand there are some, but not for all functions. I don't know what requires APF authorization. The ams command is APF authorized in my environment by doing an exattr -p -a ams to mark the ams command as APF authorized and PROGRAM controlled. Most functions in IDCAMS will still work even without these attributes. I envisioned the ams command mainly to do LISTCAT, DELETE, and DEFINE commands. Would BPX1EXM be a circumvention? (Does CBT 864 use BPX1EXM?) No, my code uses an normal z/OS ATTACHX macro to run IDCAMS program asynchronously to the main program. It basically sets up the parameters, does the ATTACHX with an ECB operand, then does a WAIT on the ECB. It is simple and relatively efficient. I use ATTACHX to isolate the main code from any problems encountered by IDCAMS without the trouble of setting up an ESTAEX, which would be necessary if I did a LINKX instead. Actually, since I don't do much but echo the IDCAMS exit code, I wouldn't even need to ATTACHX or ESTAEX, just let the ams command abend. -- gil John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
