Mark, I don't understand the question.
You have already shown the resulting disassembled code for that C.
Are you asking about how to get the disassembled code for the C library routine?
Ah! Read through the thing again, and it seems you are indeed looking for the disassembly of the library routines.
Well, I guess you want a disassembler for that. Check if there aren't any in the DECUS library perhaps?
By the way. There is no guarantee that DECC$STRCPY is written in C. But a disassembly will only give you VAX assembler anyway.

Purely out of interest, how would I diassemble a DEC C routine on
VAX/VMS? Can I use DEBUG to do this?
For example, I have the following code:
#include <stdio.h>
#include <string.h>
void main(int argc, char **argv) {
char to[32];
strcpy(to, "Hello World!\n");
printf(to);
}
If I use
BUBBLE$ cc/list/machine_code strcpy.c
I get the following:
1 1267 strcpy(to, "Hello World!\n");
D6 AF 9F 0027 pushab $CODE
D8 AD 9F 002A pushab -40(fp)
00000000* EF 02 FB 002D calls #2,DECC$STRCPY
Note that the call to DECC$STRCPY is listed, but not the code in the
routine.
I'm interested in how some of the C library routines are implemented at
a machine code level from an academic point of view.
Regards, Mark.

Mark, IIRC VAX compilers have an option that lists the assemblycode. It's either an option for /LIST or /OUTPUT.
For C the included libraries may be omitted, again a switch for the CC command

Phone V1 on VMS was a hack from the VMS MAIL utility by Paul
Agnostopolis (sp?).
Trivia question time... What other X1/T1/V1 VMS Layered Product came
from VMS MAIL?

It may have been the other way around. There were a number of DECnet
applications that started on VMS; Notes is one such. I don't remember
Phone anywhere other than VMS -- so I can't be sure about the time line
for that one.

Want any hosts added to the phone directory?
No, I actually prefer email. I'm not really into the this whole
chat/texting/instant messaging/tweeting thing. Guess I'm just old
fashioned.
But then I wouldn't be here on this list if I wasn't :-)

No, I think you got that backwards.
PHONE for RSX only exists for RSX-11M-PLUS, and it's pretty buggy and limited compared to the VMS version. I would suspect the RSX version was just a quick hack to get something phone-like to also run on RSX.
Btw, PHONE also exists for TOPS-20.
Also, I believe DECnet functionality, and PHONE as such, didn't come about until a bit later than VMS got started, so by that time, very little got ported from RSX to VMS. I would suspect PHONE to be around 80 or so. RSX and VMS was pretty much independent development by then.

Maybe it's the web-enabled directory that's the thing.. :)
But it's pretty Web 0.2, nothing fancy.
