Using SNA IMF Pass Thru

UDCs for Starting Pass Thru 

You can start Pass Thru for the following devices:

   *   Your own terminal

   *   Someone else's terminal

   *   A cluster of terminals

   *   A printer

This section gives example UDCs for each of the four ways you can start
Pass Thru.  For step-by-step instructions on editing UDC files and
setting UDCs, see "Creating and Using UDCs," earlier in this chapter.
For more information about UDCs, see the MPE V Commands Reference Manual 
or the MPE XL Commands Reference Manual.

For Your Own Terminal 

You can create a UDC to start Pass Thru on your own terminal by entering
the following lines in your UDC file: 

     PTMYTERM
     RUN TTSSON.PUB.SYS;&
     INFO="CONFIG=SNAPU#IMFCLASS;DEVID=D;LDEV=0"
     **********

Be sure to replace " SNAPU#IMFCLASS" with the SNA node name and the SNA
class nameor security class name configured for SNA IMF on your system.

Once this UDC is set, you can start a Pass Thru session on your terminal
by typing the following at the MPE colon prompt: 

     :PTMYTERM

This UDC uses the default values for  format,  priority, ANKS,  enhance,  
spriority, readto, TRACE,  pfn, and LJ2.

For Someone Else's Terminal 

The UDC that starts Pass Thru for your own terminal can be modified to
start Pass Thru for another terminal.  You just have to change the LDEV
value.  For example, the UDC to start Pass Thru for logical device 25
would look like this: 

     PTTERM25
     RUN TTSSON.PUB.SYS;&
     INFO="CONFIG=SNAPU#IMFCLASS;DEVID=D;LDEV=25"
     **********

To start Pass Thru for logical device number 25, you would type the
following at the MPE colon prompt: 

     :PTTERM25

You can also create a UDC with optional parameters.  If you make certain
parameters optional, you can use the same UDC to start Pass Thru for
various devices just by entering different parameters when you enter the
command.  In the following example, CONFIG, DEVID, and LDEV are set up as
optional parameters.  The values in quotation marks are the defaults. 

     SNAIMF CONFIG="SNAPU#IMFCLASS",DEVID="D",LDEV="0"
     RUN TTSSON.PUB.SYS;&
     INFO="CONFIG=!CONFIG;DEVID=!DEVID;LDEV=!LDEV"
     **********

After you have set the UDC, you can type 

     :SNAIMF

at the MPE colon prompt, and the values in quotation marks 
will be used for the CONFIG, DEVID, and LDEV parameters.  A Pass Thru
session will be started for your own terminal, because the default LDEV
value is 0.  However, you can change the default parameter values by
typing different ones when you enter the command.  For example, to start
Pass Thru for logical device 25, just enter

      :SNAIMF LDEV=25

and Pass Thru will begin on the terminal associated with logical device
25. 

For a Cluster of Terminals 

You can create a UDC to start Pass Thru for a cluster of terminals or a
cluster of printers.  All devices in a cluster must be the same type
(either all printers or all terminals).  The following UDC starts Pass
Thru for the terminals associated with logical device numbers 25 through
30: 

     PTCLUSTR
     RUN TTSSON.PUB.SYS;&
     INFO="CONFIG=SNAPU#IMFCLASS;DEVID=D;&
     LDEV=25,26,27,28,29,30"
     **********

After the UDC is set, you can type 

     PTCLUSTR

and Pass Thru will start for logical devices 25 through 30.  With this
type of UDC, you can bring up all the terminals on a node with a single
command.

This UDC uses the default values for  format,  priority, BLANKS,  
enhance,  spriority,  readto, TRACE,  pfn, and LJ2.

You can also use the UDC with the optional parameters to start Pass Thru
for a cluster of devices: 

     SNAIMF CONFIG="SNAPU#IMFCLASS",DEVID="D",LDEV="0"
     RUN TTSSON.PUB.SYS;&
     INFO="CONFIG=!CONFIG;DEVID=!DEVID;LDEV=!LDEV"
     **********

To start Pass Thru for the cluster of devices associated with logical
device numbers 25 through 30, enter the following command at the MPE
colon prompt: 

     :SNAIMF LDEV="25,26,27,28,29,30"

For a Printer 

The following UDC starts Pass Thru for the printer associated with
logical device number 6: 

     PRTRUP CONFIG="SNAPU#IMFCLASS",DEVID="P",LDEV="6"
     RUN TTSSON.PUB.SYS;&
     INFO="CONFIG=!CONFIG;DEVID=!DEVID;LDEV=!LDEV"
     **********

This UDC uses the default values for  format,  priority, BLANKS,  
enhance,  spriority,  readto, TRACE,  pfn, and LJ2.

If you enter only 

     :PRTRUP

at the MPE colon prompt, a Pass Thru session will be started for the
printer associated with logical device number 6.  However, you can use
the same UDC to start Pass Thru for a different printer by specifying a
different logical device number when you enter the command.  For example,
to start Pass Thru for the printer associated with logical device number
8, you would enter the following command: 

     :PRTRUP LDEV=8
