Rob,

That does address my concerns. This means my code works as well, which is nice😊.
Many thanks.

Hi Lennie,

I cannot comment too much on the SYSLOG side of things as SDSF "LOG S" just 
echoes what comes back from JES2, however we do have code to take the MDBs from 
the OPERLOG (SDSF "LOG O") and format them to emulate SYSLOG (with a bit of 
color and filtering capability added).

(o) The "S" indicator will always follow an "N" because the message text for 
both lines is taken from the same MDB log block (in fact the same MDBT object).
The decision to split the message text line is purely taken to emulate SYSLOG, 
and we could (if we wanted to) have a version of "LOG O" where we always format 
the message text in a single line. It would just mean a bit more horizontal 
scrolling on the user or bigger screen sizes (#team62x160) .

(o)  There will only be a single "S" as we split on 73 bytes of message text 
and 2x73 > maximum single WTO text length.

Hope that helps

EXTERNAL EMAIL





Greetings all,

I have spent some time examining the structure of SYSLOG/OPERLOG in order to 
produce a message scanner that can produce whole message output (i.e. 
assembling multiple lines while selecting a single message id).

I have a couple of questions that someone may be able to help me with, relating 
to single line WTO messages.


  1.  If a line in SYSLOG has the letter 'N' in the first position in 
SYSLOG/OPERLOG then it is for a single-line WTO. However, it can have a 
continuation line in SYSLOG/OPERLOG if the WTO overflows a single line. This 
secondary line has an 'S' in the first position.
Will the 'S' line always follow immediately after the 'N' line? (i.e. could 
another line come between them?
  2.  Can there be more than one 'S' line for a 'N' line?
  3.  If so, will they always be kept together?

Thanks in advance for any help.
Lennie
