A different kind of persistence?

["Dane Cox" <DCox@xxxxxxxxxxxxx>]

The last few weeks I have been reading the threads on persistence and
static variables and have actually come across a similar but slightly
different 'issue' that I thought I'd try and get some insight on.
 
I have an RPGLE program that calls a procedure contained in a module.
The procedure chains to a file and makes a determination based on the
contents of the record being chained to.  The calling program (the one
that calls the RPGLE program just mentioned) uses a job running in batch
to handle its calls.  Therefore, multiple calls are made to the RPGLE
program (and consequently the module) during the life of the job.
 
The issue is this.  If a chain to the file in the module is successful,
all of the fields from the data file are filled with the appropriate
data.  The module 'returns' to the RPGLE program which ends by setting
LR on.  Now, on any subsequent call to the module (within the same job)
the fields from the data file retain there previous values.  Of course,
once the job is restarted, the variables are re-initialized, and there
is no problem.
 
So, fields from files declared and chained to in modules retain their
data for the life of the job?  Is this normal behavior or am I just
missing something?
 
Regards,
Dane
