RE: File Pointers

["Richard Jackson" <richardjackson@xxxxxxxxxxxxxxxxxx>]

two possible problems:

1. If "write" means the RPG verb WRITE, the detail line may not have been
written into the physical file yet - use close or FEOD to make sure that the
buffer is flushed to disk.

2. the two logical files are unrelated and have independent file pointers
into the physical.

Assuming that both files are immediate maintenance, they will both contain
the same data - if the record was actually inserted into the physical, then
both LA and LB will know about the record.  If not, then not.

Small problem, is this the answer?

Program A, writes a record to the order detail file using logical LL0001LA.
Program A, then immediately calls program B, which is passed the order
number to recalculate the total order amount in the detail file to update
the order header file.  Program B uses a different logical, LL0001LB, over
the order detail file.  Program B, does a CHAIN to the first record for the
order, then a subsequent READE until end of order.

QUESTION???  Where is the pointer sitting when Program B does its first
                           CHAIN to the order detail file LL0001LB?  Is it
where the
                           last record was written or where?

Thanks for your help.

Lewis
