Chris,I tried to do some modification carefully and it now works.
It's a good beginning though I only changed the display contents
of logon screen,no color,no hilight,no other functions.
There are two questions here.
1,I checked VTAM procedure in JES2 proclib ADCD.ZOSV14S.PROCLIB(You know,
the sytem which I use for test is in fact an ADCD ZOS on lap) and found its
VTAMLIB concatenation like this: user.vtamlib
adcd.zosv14s.vtamlib
sys1.vtamlib
The user.vtamlib is empty and USSN module is in ADCD.ZOSV14S.VTAMLIB.
My plan is to place my own module in JOHNNY.VTAMLIB which resides on
a different volume and then add my own lib to the top of VTAMLIB
concatenation.
So if VTAM failed during IPL,I can vary the volume which JOHNNY.VTAMLIB
resides on offline and then restart VTAM.
Then I placed USSTAB source I modified in JOHNNY.VTAM.SOURCE and
the destination load module in JOHNNY.VTAMLIB.I modified the JCL and
submitted it to compile and link.
But the job failed. The system says it's waiting for data sets.I checked the
log and got the message:
*IEF861I* *FOLLOWING* *RESERVED* *DATA* *SET* *NAMES* UNAVAILABLE TO
IBMUSERA
DSN=JOHNNY.VTAM.SOURCE
DSN=JOHNNY.VTAMLIB
It's strange.No other users or jobs are using these two data sets,why
they're
unvailable to my job?
2,So I canceled my modification to JCL and resubmitted it.This time there is
no problem.However,after re-IPL,the new logon sreen only works when you
connect to it using port 3270.On the other side,if you use TCPIP port 23,
the logon screen is still the old one.Why does this happen?

Johnny Luo
