All I know is that the first MVS (or was it OS/390?) shop I worked with,
back in 1983, called them phases. After that shop, I was in VSE shops
until 10 years ago. Only upon returning to VSE did I first hear "load
module" and "objects". I just figured that when they moved to using
"Binder", they stopped using the old term.

z/OS has program objects and load modules. Within legacy load modules there
might be segments or overlays. But a/OS does not have phases.

A phase in z/VSE is the same as a phase in z/OS, But, the CSECT info is
not as complete as in z/OS. While z/OS has the information for the
original different CSECTs used to build the phase, z/VSE only saves the
main CSECT identification information. Restated, all the subroutines
that may have been hard-linked to the phase are in the phase, but there
is not enough information to remove or replace one of the csects.
So, when you punch the phase from z/VSE, you will see only one CSECT for
the total program.
In this discussion, the problem is that even if the COBOLII program was
linked with LE 'parts' in z/VSE, those LE 'parts' may try to use z/VSE
only pointers to branch into LE.
So, I don't think it's going to work.

What do you consider to be the MVS equivalent of a phase, and what utility are
you using to convert a load module to an object module?
Certainly you can relink (rebind) and delete extraneous csects but that's
somewhat of a manual process and still doesn't give you card images.

Don't expect it to work. When VSE punches a phase, the link deck created
includes any called modules without any way to get them out. This is in
contrast to z/OS which produces all the individual modules.

Hi,
I was asked to attempt to link a object deck from VSE in z/OS.
The program is a COBOL2 program, but the source has been lost.
The first few lines of the object deck are:
W PHASE JKHIVX52,S+X'000000'
W MODE AMODE(31),RMODE(ANY)
W.ESD .. ..JKHIVX52.§.©..÷0
After that there are many (A little over 12,000) lines that start with W.TXT
Next there are lines that start with W.RLD and a final like that starts with
W.END.
The JCL I used was
//LKED EXEC PGM=IEWL,
// PARM='LIST,XREF,NOLET,MAP',
// REGION=2M
//SYSLIN DD DSN=N623.PMKA.KPMAT.JKHIVX52,DISP=SHR
//SYSLMOD DD DSNAME=V110GAD.LOAD(JKHIVX52),DISP=SHR
//SYSUT1 DD UNIT=3390,SPACE=(CYL,(1,1))
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
INCLUDE SYSLIN(JKHIVX52)
NAME JKHIVX52(R)
I am doing something wrong?
Can this deck be linked into a usable z/OS load module?
Thanks
Gadi
