DEC does supply it with VMS - it is just not the most recent version

I am trying to print from Sun workstations (Sun-3s, running
SunOS 4.1.1), to a DEC LPS-20 printer on our network.

This printer is on the ethernet, and it is supposed to support
TCP/IP.  Its server is running DEC Print Server Supporting
Host Software, version 4.0.  BTW, the server is a VAX 4000/300,
running VMS 5.4-2.

The question is:  How do we do it?  Do I need extra software

work? 

Any help will be greatly appreciated.

Fellow VAXers,

Has anyone upgraded PHOTO or JOBLOG to use the new, standard VMS
pseudo-terminal driver?  Or, does anyone know of another utility that
performs the same function (capturing a terminal session to a file) that
uses said driver?

We are in need of a utility to do this, and would rather not install
a non-standard device driver.

I know that SET HOST/LOG will sort of do this, but we don't want to give
students NETMBX priv just for this purpose.

Date: 8 Apr 92 11:29:55 GMT

This is a summary of the answers I received on my question:

	How to SET FORWARD to multiple users in VMSmail?


1. You can use the command 
	SET FORWARD IN%"""user1@place1,user2@place2"""
   The addressees have to be in internet format and the triple quotes are 
   necessary.

2. Use the package called DELIVER

3. Install a third party mailer, e.g. MX

I used the first method and it works well. I have tried to get the DELIVER
package from VMSSERV@NYUACF.NYU.EDU, but I received a message that the package
was not currently available. Does anybody know where else I could get the
package (via mail, because I can't do FTP)?

Thanks to everybody who replied to my question.

Organization: University of Nebraska at Omaha

X-News-Reader: VMS NEWS 1.11

Does anybody know how to flush the stdin in VMS 'C'? I'm using the system();
function to run a command and would like to flush any key(s) the user might
press while waiting for the command to complete (esp. since the system(); call
takes a long time to spawn and run if there are too many people on the system
(Is there a faster alternative to using the system() call? I'm using VMS 5.4.3)
Also if anybody knows how to disable the Ctrl-Y and Ctrl-Z from within a 'C'
program I would be greatly appreciative. I'm modifying a VMS menu program (5000
lines) that I've wrote and if anybody is interested in running it they can do
so by telneting to zeus.unomaha.edu and login as a guest then typing "window"
at the $. The program is located in perm$5:[conslt24.public]. Please feel
free to use or to get a copy of it. Back to my question I'm doing something
similar to the next program and I can't figure out why it's not working.


#include <stdio.h>

main()
{

char test;
int array[10];

	printf("\n Type a letter: ");
	scanf("%c",&test);	/* wait until I'm ready		      */

	sleep(5);		/* while waiting for 5 seconds        */
				/* Type a string and press <enter>    */

	fflush(stdin);		/* flush standard input (keyboard)   */

	scanf("%s",&array);	/* read what's in the input buffer    */

	printf("\n%s",array);	/* will print the string typed before */
				/* flushing the stdin		      */
}


Any suggestions are welcomed and are greatly appreciated.

What's to prevent you from setting forward to a logical name, whose
definition is something like:

$ define /system forward_username user_1,user_2,user_3

I've used this before, but there is a problem when receiving mail from 
foreign systems using  MAIL11 (from an Ultrix machine for example).  This
doesn't seem to work, so the usefulness of this approach is limited.

Subject: Descriptors and VMS C (again!)
Date: 11 Apr 92 19:37:33 GMT
Distribution: world
Organization: The Internet

Someone here posted a question on the RTL routine lib$find_file a while ago.
This got me interested in the RTL and programming using descriptors. Since C is
my preferred language, I decided to experiment with several RTL functions. I
was able to successfully write several programs using string descriptors.
However, there is one function which still doesn't work right in C for me. I
have managed to make it work in pascal, but for some reason I can't find the
error. The output I get for this program (which usest the routine
lib$find_file) is just a bunch of newlines. I don't understand why this
happens. We don't have a VAX C manual here, so I try to learn by looking at
other people's code. In fact, the loop in the program here is basically one I
saw on INFO-VAX a while ago.

/* program to list files in a directory */

#include <stdio.h>
#include <descrip.h>
#include <rmsdef.h>

int main (argc, argv)
        int argc; char *argv[];
{
        long int status,
                 rv,
                 context;
        char    *file,
                *dir,
                tmp_file[255],
                tmp_dir[255];

  $DESCRIPTOR(directory, tmp_dir);
  $DESCRIPTOR(filename, tmp_file);

  file = (char *) malloc(255);
  dir = (char *) malloc(255);
  strcpy(dir,"*.*;*");
  descriptor(&directory,dir);
  descriptor(&filename, file);
  while ((rv = lib$find_file(&directory, &filename, &context)) != RMS$_NMF)
   {
     printf("%s\n",file);
   }
 status = lib$find_file_end(&context);
}

descriptor(desc,str)
        struct dsc$descriptor_s *desc;
        char *str;
{
        desc->dsc$w_length=strlen(str);
        desc->dsc$b_dtype=DSC$K_DTYPE_T;
        desc->dsc$b_class=DSC$K_CLASS_S;
        desc->dsc$a_pointer=str;
}

/* end of program */

Does anyone see something wrong with this??? Thanks a lot in advance!

I am trying to run a window application on a DECStation (Ultrix 4.2) and display
it on my VAXstation (VMS 5.4). 
On ULTRIX I do (username FOO):  
                  >DISPLAY=vax::0.0
                  >export DISPLAY
                  >/usr/bin/X11/xclock (only an example)
                  >
And I get the error Xlib: connection to "vax::0.0" refused by server
                    Xlib: Client is not authorized to access server
                    Error: Can't open display

Now, on VMS I specified in the Session managers security customization : 
"node=vax, user=foo, transport=decnet". The display only works if I 
specify "user=*".
If I use TCPIP as transport mechanism, it never works, even with "user=*". By the
way, with TCPIP, "user=*" is THE only way to do this.
Both systems know each other in their DECnet databases. For TCPIP we run UCX on
VMS and Internet addresses are also compatible.
My worries are great, because all this used to work before and I can still 
display applications from VMS to VMS and from VMS to Ultrix.

The Identifier IDX has to have the attribute RESOURCE, and the users
need to have the Identifier GRANTed to them with the attribute=RESOURCE.

Then set the owner of the directory to IDX.  If you have defined quotas
on the disk, be sure that you create a DISKQUOTA entry for the
identifier and give it lots of quota. 

$ SET DEF SYS$SYSTEM
$ MCR AUTHORIZE
MODIFY/IDENT/ATTRIBUTE=RESOURCE IDX
MODIFY/IDENT/ATTRIBUTE=RESOURCE/HOLDER=xxxxx IDX
   --- repeat for each user ---
EXIT
$ SET FILE COMMON.DIR/OWNER=IDX

That should get you going.

RMS was never packaged separately on VMS, though it may well have been on
RSX for the PDP-11s.  FILES-11 ODS Level 1 was used by RSX - VMS implemented
it for compatibility, but by default you get level 2.  Nowadays you can
tailor off the Level 1 ACP if you don't want it.

Like another poster, we've got a lot of C programs we've ported from UNIX
to VMS.  We figured out that we needed to define the programs as foreign
commands in order to pass command line arguments to them.  Our next questions
are:

    - Is there a way to run a foreign command as a detached process?

    - If a program is linked "/DEBUG", is it possible to run the program
      via a foreign command without having it come up in the debugger?

Just a friendly correction... you will look long and hard for a definition of

I would say not, as INSTALL *used* to use the square brackets.  It seems to
me that this changed back in version 4 of VMS, but it might have been V5.0.
Angle brackets have always been supported by RMS, I thought for backwards
compatibility with the pre-VMS operating systems.  (Similary, one can
reference directories named "[xxxyyy]", where xxx and yyy represent octal
digits, as "[xxx,yyy]" excluding leading zeros.  Thus, "[0,0]" is the same
as "[000000]".  (There might be cases where software doesn't deal with this
correctly when found in a rooted device specification, though.)

Anyway, I always figured that the change in INSTALL was done more as a
"just because" reason.

  Can anyone out there tell me about their applications using more than
 one screen on a workstation with the SET DISPLAY/SCREEN command ?  Is
 this functionality very common in the VAX world yet?

  I hear it needs extra hardware which I might be willing to go for.
 Sounds like just the ticket....

Rename [sys0] to something else, for example [oldsys], then your ok. If you
wissh to use this disk again as systemdisk you have to rename it back to sys0.
We had done this for a MV2000 in a cluster, works fine.
