Re: S/36 MRT programs (some questions)

["Marc Zylka" <mzylka@xxxxxxxxxxx>]

Thanks, for those who responded, for the responses.

Pete,

  This must have been one pain in the butt to test and code.  The programs
I'm looking at seem to have been
designed to take advantage of the memory savings only.  I did see one case
where a contract number was
being processed for all 5 (KNUM=5) sessions but I'm not sure why.  I'll have
to look at that closer.  It's
obvious there's more to look at than I thought.  Hmm, maybe I'll give it to
our contractor.   ; - )

Thanks, Marc

with records being left locked. Make sure that record locks are always
released. Control records that contains a values that are updated frequently
can cause problems. Also beware of deadlock situations.

but it could also be because the variable is used to communicate between all
attached sessions. Next invoice number, next record number, etc. You need to
figure out the usage of each field that is not defined in the save data
structure and each indicator that is not saved. You may need to use a shared
user space or data area to provide interprocess communication, and if you
do, you'll need to either explicitly move values to/from it, where this had
been handled implicitly before, or pass pointers to the external shared data
space and synchronize the access to it, thereby emulating the behavior of
the MRT in your code.
