Re: More Help Files

 

Hi Dave,
I see that the VM/370 LKED?and GEN3705 modules are made from DMSLKD, DMSGRN, and DMSNCP.
DMSZAP can?patch?a LOADLIB file. The only 'loader' function in VM/370 is to read a 3705 control program
module and write it to a page-format core image with the SAVENCP command.?

A relocating loader for CMS was not added until VM/SP.

Bob,

I am not so sure that it can¡¯t be loaded or executed! I would have thought if the LOADLIB was assigned to the correct DD then SVC ?6/LINK Macro would load code from it.

In addition I was hoping to fix MVS version the ASM3705 assembler so it works under VM. That appears to be the only part of the NCP support that we are missing.

There is a copy of the MVS version in one of the MVS groups. The CMS interface module exists in CMS¡­.

¡­ and lastly I hate ?having undocumented programs¡­.

Since LKED?produces an object which?cannot be loaded or executed in VM/370 CMS,

why do we want to document it??

It can't do too much harm. They were generally created on VM/370 where there is no spell check etc.

No, I only looked at stuff on the "Y" disk. The next step will be to check what is on the "S".?
The Linkage Editor is documented in

GC20-1801-10_VM370_Sysgen_Rel_6_Jan80.pdf

Which you will find on "BitSavers". In there it says, on page number 310 (page 341 in the PDF)

Only a subset of the possible linkage editor control statements are meaningful in CMS. .Since the CMS interface program cannot examine the input data for the LKED command, all of the control statements are allowed, even though several of them result in the creation of a load module file which cannot be used under CMS. For both command options and control statements, see the publication "OS/VS Linkage Editor and Loader"

which leads me to believe that the Linkage editor is a direct port of the OS/VS Linkage Editor. It won't take long to create a help file from the manual.
