RE: Opening the same file twice

It's an old COBOL habit that's hard to break.  The file contains both
summary and detail records.  In order to calculate a field in the summary
record, I have to accumulate the field from the details.  I am reading the
summary record, then reading the details to accumulate the field then
updating the summary.  I don't have a second logical I can use and I don't
want to create another if I don't have to.

Actually, thanks for asking.  Writing this out has given me the solution I
should use and I won't need to open the file a second time.  I'll just
rearrange the order of my process.  That is, I'll accumulate the detail
records first, then read and update the summary record.

Thanks for all your responses.

RPGLE you would be USROPN in the keyword field.

Why twice?  If it is because you want to do an override consider also 
using EXTNAME(MyVar) or EXTMBR(MyMbrVar).  Saves that pesky CALL QCMD to 
OVRDBF.
