Description
&NUMLNES
The largest line identification number (the number of teleprocessing lines).
&NUMRJE
The number of remote terminals.
&TPBFSIZ
Teleprocessing buffer size (520 to allow operation in 512–byte mode).
&NUMTPBF
The number of teleprocessing buffers.
&NUMBUF
The number of I/O buffers is increased by five for each active remote terminal.
&PRTRANS
Print line translation should be set to NO to allow printing of lowercase letters.
&LINECT
The maximum number of lines per page. A value of 0 suppresses automatic page
overflow. You can override his value by a JOB card parameter or a JOBPARM
control card.
&TPIDCT
Specifies the number of print lines on each separator page.

In an SNA environment, the 4235 LPS emulates a 3777 Model
3 communications terminal. The 4235 LPS may be defined in a
BSC environment as a Remote Job Entry (RJE) terminal operating
in any of the three modes available: 2770, 2780, or 3780. As a
remote terminal, OS/MVS and JES2 facilities support the 4235
LPS.
The 4235 LPS is defined to a JES2 system using standard JES2
system generation statements and procedures. The five–step
process requires only the addition of several generation
statements to the JES2 initialization deck.
1. Review the host computer system global parameters and specify
the appropriate values.
2. Specify the remote terminal parameters (RMTnn).
3. Specify the remote printer parameters (Rnn.PR1).
4. Specify the remote punch parameters (Rnn.PU1).
5. Specify the communication line parameters (LINEnn).
Step 1.
Specify the appropriate values for the following JES2
parameters:
