From: IBM Mainframe Discussion List On Behalf Of Edward Jaffe
This topic has been discussed numerous times in this forum.
In the past I used a 62x132 alternate size. But, after
hearing some valid arguments for more columns, recently
changed to 62x142 for my alternate size. I also use 62x80 for
my primary (default) size. But, that's another topic entirely ...
Whenever I try a "non-standard" default screensize, I am unable to log
on to TSO or Netview Access. TSO "ignores without comment" my password
on the TSO/E Logon Panel, and Netview Access produces message "EMS1010A
Enter your user ID." despite my having entered userID and password on
its logon panel. Don't know if we're back-level on z/OS maintenance or
our terminal emulator is defective, but the emulator happily allows
defining arbitrary screensizes for both default and alternate. One
other anomaly I notice is that the VTAM USSMSG10 screen *always*
displays in 24x80, regardless what default screensize I specify in the
emulator.
This too has been discussed previously.
Without OA17477, TSO/E allows you to logon with a non-standard default
geometry so long as the total buffer size does not exceed 4K. Beyond 4K,
the emulator sends 14-bit buffer addresses which are not understood by
IKJEFLNL. Therefore, the upper limit for the default screen size is
51x80. OA17477 changes IKJEFLNL to recognize and process 14-bit
addresses, raising the practical limit on default screen size to 204x80.
If you use ISPF, the maximum number of rows supported is still only 62.
:-( So, for ISPF users, the net effect of OA17477 is to add an
additional eleven rows.
Netview is another story. It is the "weak sister" here and (quite
remarkably) supports only 24x80 default size! I argued for and received
a modification from Netview development to support more rows. This
modification is available from level 2. See below:
++ USERMOD(ANSSIZE) /* 5697ENV00 */ .
++ VER (Z038)
FMID(HPZ8500) PRE(UA15444) .
++MOD (DSIPSQRH) DISTLIB(ACNMLINK).
For more information, please see

(mind the wrap).
BTW, which 3270 emulator do you use that allows specification of both
default and alternate sizes?
