Define "parallel run".
IEAMDBLG reads from the OPERLOG stream (SYSPLEX.OPERLOG), not JES2 SYSLOG.
As long as the legacy tools accept a longer LRECL, they will work as
the record format is the same as JES2 SYSLOG (HCL for 2-digit years
or HCR for 4-digit years), but with a longer data length and fewer or
no continuation records.
The 255 LRECL is driven by use of the MVC instruction to build the
output record and could be extended further by a more extensive
modification using looped MVCs or MVCL.
** Local revisions:
*
* 1. LRECL of SYSLOG increased from 132 to 255 (could be longer,
* but moves would have to be changed from MVC)
* 2. COPY keywords "YESTERDAY" and "LASTWEEK" added
* 3. time/date capture moved to initialization
* 4. LOGBUF moved to end of data due to length
* 5. DCBR added to relocate sequential buffers above the line
* 6. original lines commented to allow regression checking
* 7. 0405 abend changed to warning message - see NOTEMPTY,
* GAPORDEL, LOSTDATA, and LOSTMSG portions of the code
*

Hi Michael,
By any chance, is this something that can be setup like a parallel run?
Main recording is the default behaviour, 255 long is secondary
write, so it helps analytics.
This way, legacy tools won't be upset by the long lines and changing
message format.
