4KB size limit for DCL commands doesn't work

Hi,
http://h71000.www7.hp.com/doc/732FINAL/aa-rv8xa-te/00/00/20-con.html#babdggid

I have a problem with line size limit after using command:
READ/PROMPT = "Continue? Y/N: " SYS$COMAND CONT

After this command the same DCL session change line limit from 4095 to 256 bytes.
Does anybody know why?

I've running VMS V7.3-2.

Corrrection:

... of course.

Petr,

could you provide an example to illustrate what you are doing and what kind of problem/symptom/error message you see ?

I tried to reproduce it using V7.3-2 and V8.2 and was not able to do so.

Do you have plain V7.3-2 or are any patches installed?

Petr,

I can reproduce the error.
After the read command the limit becames 512 bytes. I tested this on an "real" terminal (OPA0 and TTA0) and on a DECterm (FTA) and also on an DECnet (RTA) remote terminal.
The strange thing is that on the DECnet remote terminal I cant reproduce the error.

After the RMS-W-TNS error you receive another error if you tray to recall the long line (or with RECALL or simply with up arrow). The error is:
%SYSTEM-F-BADPARAM, bad parameter value

My system has no last paches installed!

Petr,

I can also reproduce it on V7.3-2 and E8.2. The problems is NOT the symbol length (SHOW SYMBOL b), but the interactive command line input, which fails with

%RMS-W-TNS, terminator not seen

after 512. bytes.

I know someone, who's probably interested in this ;-)

Hi, thanks for interest.
I've 3 months old patches (attachment). It looks as some problem with user buffer. I can reproduce this from common VTA100 terminals (decterm, aterm, PowerTerm).

Bojan,
BADPARAM it's inference of incomplete command.

Volker,
... and when will be fix? :-)

To all:
I always use TELNET sessions to connect my terminal. Not DECNET.
