RE: Passing data structure to batch job

Will the DS ever be larger than 5000 characters? If not then why not just
create a command that accepts a single parm and use the command on the
SBMJOB?

I will give it a try to suggest something easy and that works in all
circumstances:

Use a file for which the record definition is like the data structure
mentioned plus one field that is the key (let's say a 15 digit number
field). The short running program puts the values to pass to the long
running program in a record in that file. Chooses whatever method you
which to generate the key value (stored in a data area, position yourself
on the last record and do a read previous ...). Now the short running
program just pass the key value to the long running program et voila.

Just make sure that the long running program deletes the record when it is
finished.

I know that using a file for parameter passing is not the most efficient
way but we were ask for an "easy" way and this way is easy and will work
even if there was several short running jobs calling several long running
jobs.

Another advantage is that that way, you are sure that both the calling and
called program use the same structure for the parameters (type, length,
position ...).

So this is my 2 cents

Hope this help
