When you sign-on an AS/400 system, you are interacting with

interactive jobs(e.g.QINTER). The System-jobs which are

presubmitted are called batch jobs(e.g.QBATCH, QSPL, QCMN etc.,)

If u want to know whether a job is in Interactive or Batch,

u can use RTVJOBA command with attribute JOB-TYPE on that job.

if it has a value '1' = Interative; '0' = Batch.

you can change a Batch-job to Interactive-job as long as it

is in JOBQ(by changing the environment on CHGJOB(opt-2)

command to QINTER or QPGMR); once it's active we cannot

change the type.
